SIEVERT 1504IS Liquid Propane Hose

This 4 ft coupled assembly is built for liquid propane delivery in welding and heating tasks. It suits technicians who need a short, flexible connection between a regulator and a torch. The hose meets EN 559 and ISO 3821 standards for gas equipment safety.

Brass FLH fittings on both ends

Both 9/16 in FLH fittings are brass, giving corrosion resistance and a reliable seal on standard propane hardware. The rubber tube and TPE cover handle a maximum working pressure of 350 psi at 70 F. The black cover resists abrasion and weather during daily workshop use.

1/4 in bore for propane flow

The 1/4 in inside diameter sets the flow capacity for liquid propane applications. Buyers needing higher flow rates or a different gas grade should select a hose with a larger bore or alternative certification.

What pressure does the EN 559/ISO 3821 rating allow at 70 F?

The hose is rated for a maximum working pressure of 350 psi at 70 F under the EN 559/ISO 3821 standard.

What thread size do the brass FLH fittings use?

Both ends have 9/16 in brass FLH fittings designed for standard left-hand propane connections.

How do you attach the fittings without damaging the rubber tube?

Tighten the 9/16 in brass FLH nuts by hand first, then finish with a wrench — over-torquing cracks the rubber liner.
