This 35" propane pigtail hose connects a propane cylinder to a regulator via a POL fitting at the cylinder end and a W20 (5/8" LH) nut at the regulator end. This 35" pigtail is used as a replacement hose for caravan, motorhome, domestic and commercial LPG setups. A key difference between this pigtail and a standard pigtail is the inclusion of excess flow valve protection. If the excess flow valve detects a rapid increase in gas flow beyond safe limits (i.e., due to a failed fitting or damage to the down-stream hose), the excess flow valve will immediately reduce gas flow.
A second feature included in the design of this pigtail is a non-return valve. In cases where multiple cylinders are connected to a single regulator, either directly or indirectly through an auto-changeover device, back-flow of gas through the regulator could lead to serious safety concerns. The non-return valve prevents this type of back-flow from occurring.
This hose has been manufactured to meet the requirements outlined by European Standard EN 16436-1 Class 3. The rated working pressure of this hose is 30 Bar with a maximum burst pressure of 90 Bar. With this level of rating, even in extreme circumstances, there is no chance of failure due to excessive pressures. The hose is manufactured within the United Kingdom and has been approved for use with propane by Calor Gas. Approval from a recognised regulatory body such as Calor Gas may be necessary to demonstrate compliance with regulations related to insurance and/or habitability checks for your LPG
The primary reason for using a protective valve is to have an additional level of security when compared to the standard "pig-tail". Having both non-return (one-way) and excessive flow protection in a single hose assembly reduces the number of individual safety devices required to be fitted and maintained. It is also the type of specification which will often be inspected during the habituation report and Gas Safety Inspection process.
As a Calor approved product, manufactured within the United Kingdom, provides a documented history of compliance should such evidence ever be required. The fact that the product has been tested at a maximum operating pressure of 30 Bar, whilst a typical residential system operates under much lower pressures, provides a true margin of safety as opposed to merely being at or near the limit of operation of the hose.
