20" Propane Gas Pigtail - NR POL x 1/4" Inverted Flare
You might also like:
This 20" propane pigtail connects an LPG cylinder to a regulator or adaptor fitted with a 1/4" inverted flare connection, with a non-return valve to stop gas flowing back into the cylinder and an excess flow valve to shut off supply if flow exceeds a safe rate. Built to EN 16436-1 Class 3 and approved by Calor Gas for use with propane cylinders, it suits caravan, motorhome, domestic and commercial LPG installations using this connection type.
The non-return valve prevents backflow into the cylinder, while the excess flow valve restricts gas supply automatically if something goes wrong, such as a hose failure downstream. Rated to 30 bar working pressure with a 90 bar burst pressure, it's built for regular propane use rather than just meeting the minimum standard.
The connection is a 1/4" inverted flare (7/16" x 24 Whit form), which differs from the more common W20 or BSP fittings. As an NR pigtail, this version is intended for use where backflow prevention is required at the cylinder connection — worth checking your regulator or adaptor thread before ordering to make sure it matches.
Non-return and excess flow protection give this pigtail a solid safety margin for propane systems, and the EN 16436-1 Class 3 build with Calor Gas approval confirms it meets recognised standards for propane use. The 1/4" inverted flare fitting makes it a straightforward choice for regulators and adaptors using this thread type, and the 5-year warranty reflects confidence in long-term performance.
