This 35" propane pigtail uses a straight-through POL x POL connection, joining two POL fittings directly with no reduction in bore and no fitted valve. It's designed for unrestricted flow-through between compatible cylinders, regulators, wall blocks or changeover systems — most commonly used when expanding a cylinder installation with a Y-piece or Tee-piece to add extra cylinders to an existing setup.
Unlike an NR (non-return) pigtail, this straight-through version doesn't include a non-return or excess flow valve. That's intentional — it's built for linking cylinders or extending a system where a valved pigtail is already providing that protection elsewhere, not for replacing one. If you need a single hose with built-in backflow and excess flow protection at the cylinder connection, an NR POL pigtail is the correct specification instead.
The hose is manufactured in the UK to EN 16436-1 Class 3, rated to 30 bar working pressure and 90 bar burst pressure, and it's Calor Gas approved for use with propane. Every assembly is pull and pressure tested during manufacture, with a self-adhesive identification label fitted for easy checking later. At 35" (889mm), it offers more reach than the 20" version, giving room to route between cylinders spaced further apart or connect into a Tee-piece without the hose being awkward to dress.
If you're expanding an existing LPG installation, this is a more practical route than upgrading the regulator or changeover unit — the straight-through design and Tee-piece compatibility let you add cylinder capacity to a system that already has valve protection built in elsewhere. Every hose is pull and pressure tested individually before it leaves the factory, and the EN 16436-1 Class 3 rating gives it a wide margin over what a domestic or commercial propane system will see day to day. At 35", it offers more flexibility than the 20" version for installations that need the extra length. Being UK made and Calor approved also makes it straightforward to document for gas safety checks.
