Quick Connect Lp Gas Fittings
Natasha Mulhearn
Quick-Connect Fittings are also called push-to-connect, push-fit, or SharkBite fittings. They allow for a quick and easy tubing connection with a locking collet design that grips the outer diameter (OD) of various tubing and pipe sizes. These fittings are designed for OD polyethylene and PEX tubing, as well as copper and PVC pipes.
Elbows are attached to pipes to change the direction of flow. Types of elbows include long-radius or 90 elbows and short-radius or 45 elbows. A 90 elbow is more common because it reverses the flow completely and keeps the tube from kinking.
DMfit fittings are often used for water purification and food service. These fittings are non-toxic and safe to use in drinking water applications. They are easy to disconnect and maintain and can be connected and reconnected repeatedly.
Swagelok offers a variety of quick connect fittings that enable quick, simple operation without twisting, turning, or wrenching. Engineered to minimize spillage and air inclusion, our quick connects are available in a wide range of configurations, stem and body connectors, including single-end shutoff and double-end shutoff models, with an array of end connections.
Lol, air hose quick connectors are designed to seal throughout a broad range, from very low pressure to very high pressure, just as you see in common use everywhere with everyone who uses air compressors and air tools
This week we take a look at the most common connectors used for home brewing systems on pumps, kettles, and fermenters. I compare Tri-clover, Camlock, Blichmann NPT and Quick Connect options for your brewing systems. We look at the advantages and disadvantages of each.
The advantage of Camlocks is they are very quick to connect and disconnect and the locking mechanism provides a solid water-tight seal. They are much faster to connect than screw-on NPT connectors. The disadvantage is that they do get hot on locations like the brew kettle, so you do need to wear gloves when handling hot connections. Also because one end has an NPT screw adapter on it, you still need to occasionally clean that threaded NPT adapter out as its not sanitary.
Tri-Clover fittings are sanitary and are widely used in commercial brewing applications as well as many food/beverage applications. The connection consists of two tri-clover connectors, a separate silicone seal, and a tri-clamp that holds the three pieces together. They are available on some stainless homebrew fermenters where sanitation is important as well as commercial level brewing equipment.
Like Camlocks, they also absorb heat, so a tri-clover kettle is going to get pretty hot and likely require that you have gloves to reconnect it. Finally tri-clover fittings are generally more expensive than other alternatives. Since each connection requires four pieces (two connectors, a gasket, and a clamp) they are not as cheap as NPT or Camlock connects.
These connectors have the same advantages/disadvantages of camlocks, including a typical NPT adapter connection, heating up of the connector and quick-connect ease of use. I personally prefer the camlock for the positive locking mechanism, but these in practice are very similar to a camlock.
If you have a three tier brewing system with two pumps where you may actually make and break several connections while brewing, it may be more important to have quick connects like the Camlock installed so you can change things over quickly.
It may also be perfectly appropriate to mix connectors. For example I have a SS Brewtech fermenter which has tri-clover fittings on it. So I have one special hose that connects from my Therminator plate chiller (an NPT fitting) to a Tri-clover fitting so I can chill and fill the fermenter from the bottom. I have another special tube with a tri-clover on one end and keg connector on the other end that I use to pressure-transfer beer from my fermenter to fill a keg.

Agilent InfinityLab Quick Connect and Quick Turn fittings are truly high-pressure, finger-tight fittings for connections onto columns or other instrument positions for your HPLC & UHPLC. These HPLC column connectors have innovative spring-loaded design to ensure zero-dead-volume connection, helping you avoid the broadening or tailing of peaks, loss of resolution, and overall poor chromatographic performance associated with poorly connected fittings.
InfinityLab Quick Connect UHPLC fitting is finger tight up to 1300 bar, for UHPLC column connections as easy as pressing a lever.
For harder-to-reach areas on your LC instrument, the InfinityLab Quick Turn fitting produces either a finger-tight connection (up to 400 bar), or a 800 bar connection with a mounting tool (P/N 5043-0915), or a 1300 bar connection with a wrench.
Agilent InfinityLab Quick Connect fittings and Quick Turn fittings use a unique, spring-loaded design. The spring of these finger-tight fittings constantly pushes the capillary towards the receiving port. The spring-loaded mechanism ensures a zero-dead-volume column connection for UHPLC and HPLC systems to avoid poor chromatography, such as peak broadening or tailing, split peaks, and carry over. The fittings are reusable and can ensure perfect connectionsfor up to 200 uses.
Poorly connected fittings are one of the top reasons for broad or tailing peaks, loss of resolution, and overall poor chromatography. Perfect connections can be created quickly and easily, without any tools, using our finger-tight fitting for UHPLC and HPLC analysis. Ideal for column connections that you connect and disconnect most often, there are just three simple steps:
It is important to use Quick Connect and Quick Turn fittings with the proprietary capillaries specifically designed for them. The Quick Connect fitting requires a capillary with a spring and a PEEK component. The Quick Turn fitting needs a capillary with a long socket due to its internal spring action. Depending on your application needs, you can select from Quick Connect/Quick Turn capillaries made from stainless steel, PEEK-lined stainless steel, and MP35N.
I was tasked with watering my carrot seedlings yesterday, and figured I would give my new Gardena soft spray garden hose nozzle a try. Gardena hose-end products have a quick-connect fitting built right in, and so I attached the included quick-connect socket to my hose.
I have used quick-disconnect fittings with water cooling loops before, and they never failed to behave as expected. If I wanted the connection disrupted, it just worked. When I wanted things reattached, it just worked. I had similar expectations for these Gardena quick connect sockets, but things worked out differently. In hindsight, I realize that my experience my water cooling lines involved pumps that were de-energized when I was working on them, and a water reservoir with small air gap provided relief for any built-up pressure.
Everything is made more difficult by not having flat surfaces to press together. Grabbing the hose end, which is a good size on my swivel-handle Flexzilla, depends on friction to apply force in the direction needed, and both of my sprayers have smooth and angled tops. As a commentor suggested, it would be easier if one of these items were immobile rather than both being handheld.
These attempts are also different because I used my new Hozelock sprayer with metal quick-connect fitting. The Gardena, shown above, has a plastic stem, and I find myself holding back in fear of breaking it.
Now on my 1.3 acre property any and all hose lengths can interchange quickly, all quick connects will flow fully when not connected, and all my hoses have a small isolation valve at the end just upstream of the quick connect.
You might consider also adding a pressure relief valve set at 75 PSI to protect in the future if the new/old pressure regulator malfunctions in the future. I added one connected to cold water supply at laundry room washer connections. Easy to do with brass hose y-splitter and similar shutoff valves. PRV valve discharge is tubed into the wall drain for the washer. Can also do at a mop sink too.
Fred, you are correct. Prevost makes both a valved and unvalved version of their quick disconnect coupler. I can say from first hand experience, it is quite difficult to swap out attachments on the valved coupler, although not impossible.

I gave up on the shutoff type of disconnects as they are hard to connect with high water pressure and add flow/pressure restriction. Consider using a shut off valve followed by a quick connect (I like Orbit 58117 connectors). I have a valve on the end of each hose to make it easy to change nozzles, sprinklers, etc. I had good luck with the Gilmour all brass ball valves. The ones I have from 2011 have brass handles too and have lasted great. The new ones have plastic handles so they may be less durable. There are some other brands with brass handles. A little pricey at $10 to $15 but they last a long time.
I slipped in the mud 3 times today, going back and forth to the spigot at different times. The area was still very wet from yesterday, and more water was added today from continued leaks. I think the Suncast does a decent job for the money, but it seems that spending more does provide immediate benefits, proven by the 2-year-old Flexzilla hose attaching to the spigot without a drop of water being spilled.
I have resort to this method before. It is still a pain and likely to squirt water everywhere but it certainly does help. Beside using the aquor system I found that using a shutoff valve close to the quick connect, like many other have commented, is a much easier way to connect/disconnect.
Like others have said, the house pressure regulator is considered a wear and tear item.
A friend replaced an older water heater because it leaked through the pressure valve at the heater, even after the valve was replaced and after a new water heater did the same thing a plumber he asked said check the pressure valve and sure thing is was bad.
