Suburban DCRLP-PT144HP High Pressure Propane Hose 1/4" ID x 144" Long, 3/8" FPT x 3/8" Female Flare Swivel

The Right Hose for Tank-to-Regulator Connections

Many RV propane systems rely on a high pressure section of hose running from the POL or ACME fitting at the tank outlet to the inlet of a two-stage regulator. This is a high pressure, liquid-phase or vapor-phase segment of the system -- it must be rated and built accordingly. The Suburban DCRLP-PT144HP is purpose-built for that role.

At 144 inches (12 feet), this hose gives you enough reach to route cleanly through a storage compartment, around a chassis rail, or across a larger propane bay without splicing or adding extra fittings. The 3/8" female pipe thread (FPT) end connects to threaded regulator inlets and manifold ports, while the 3/8" female flare swivel end mates to a standard male flare fitting at the tank valve or pigtail adapter.

End Fittings Explained

Getting the fittings right on a propane hose is critical -- a mismatched thread type is a leak waiting to happen. Here is exactly what you are working with on the DCRLP-PT144HP:

• End 1 -- 3/8" FPT (Female Pipe Thread): This is a straight female thread, typically connecting to the male NPT outlet on a two-stage regulator body or a manifold fitting. Apply approved gas-rated thread sealant (not PTFE tape on flare seats) to the male counterpart before assembly.
• End 2 -- 3/8" Female Flare Swivel: This connects to a 3/8" male flare fitting, typically found on a POL-to-flare adapter, an ACME-to-flare pigtail, or a bulk tank valve with a flare outlet. The swivel design lets you tighten the nut onto the flare seat without rotating the hose -- preventing kinks and body stress.

Typical Installation Scenarios

This hose is used in applications where the propane source and the regulator are not in close proximity -- common in larger coaches, custom builds, and situations where the regulator is mounted away from the tank compartment. Typical uses include:

• Connecting a horizontal or vertical propane tank to an exterior-mounted two-stage regulator
• Replacing a cracked, kinked, or age-degraded high pressure supply hose on an existing Suburban-specified system
• Custom propane installations in cargo trailers, toy haulers, or van conversions where extra hose length is needed to reach the regulator
• Extending tank-to-regulator reach in dual-tank systems with a switchover valve

Inspection and Replacement Guidelines

Propane hoses should be inspected at least annually and replaced any time you observe:

• Visible cracks, cuts, abrasion wear, or soft spots in the hose body
• Discoloration or blistering from heat exposure
• Corrosion or deformation at either end fitting
• Any detectable propane odor at rest (system de-pressurized) near the hose or fittings
• Hose age exceeding 10 years from date of manufacture (check stamp on hose body)
