GASPRO 15-inch RV Propane Hose Replacement 2-Pack — Pigtails with QCC-1 Tank Nut and 1/4" Male Inverted Flare, Brass Fittings

The GASPRO 15-inch RV propane hose is a durable pigtail replacement with a QCC-1 tank nut and a 1/4" male inverted flare end, sold as a two-pack for dual LP tank systems.

This pair of 15" hoses is built to reconnect or replace the short supply lines between your RV's dual propane cylinders and a 2-stage auto changeover regulator. Each hose uses the industry-standard QCC1 (ACME) nut for the cylinder side and a 1/4" male inverted flare fitting for the regulator inlet — a common configuration on many Flame King, Camco, Fairview, and Marshall Excelsior regulator models. Constructed with weather-resistant rubber and solid brass fittings, these pigtails aim to balance flexibility, corrosion resistance, and a straightforward, tool-free hookup.

How do these hoses fit my RV dual-tank setup?

They are designed specifically as replacement pigtails for dual LP tank systems using a 2-stage automatic changeover regulator. The tank end uses a QCC-1 (ACME) nut that screws directly onto standard RV cylinder valves, and the other end is a 1/4" male inverted flare that attaches to most regulator inlets that require an inverted flare — not NPT.

• QCC-1 (ACME) tank nut — compatible with standard LP cylinder valves.
• 1/4" male inverted flare — matches many 2-stage auto changeover regulators.
• Works with travel trailers, fifth wheels, pop-ups, and motorhomes.
• Not compatible with regulators requiring NPT thread — verify your inlet.

What materials and construction features ensure reliability?

The hose body is a flexible rubber compound formulated to withstand outdoor conditions, while both end fittings are machined from solid brass for improved corrosion resistance and leak integrity. This combination keeps the line pliable across temperature swings and reduces the chance of fitting deterioration over time.

• Weather-resistant rubber hose resists cracking and kinking.
• Solid brass fittings offer durable, corrosion-resistant connections.
• 15" length provides a tidy fit without excessive slack under tank covers.
• Rated for standard LP system pressures used in RV applications.

How easy is installation and maintenance?

Installation is intended to be quick and tool-free: hand-thread the QCC-1 nut to the cylinder valve and push the 1/4" inverted flare into the regulator inlet, hand-tightening as designed. After any installation or tank swap, perform a soap-and-water bubble test to confirm there are no leaks. Replace hoses immediately if you find cracks, stiffness, or noticeable odors, and consider swapping them every 5–10 years as a preventative measure.

• Tool-free hand-tighten ACME nut to cylinder valve.
• Attach 1/4" inverted flare to regulator inlet — no pipe tape needed.
• Always perform a soap-bubble leak check after installation.
• Recommended replacement interval: 5–10 years or sooner if compromised.

Why buy the two-pack and what support is available?

These come as a 2-pack so you can outfit both cylinders in a dual-tank arrangement or keep a ready spare for fast swapouts. GASPRO backs the product with customer support and a track record of user reviews from RV owners and liveaboards who rely on consistent propane flow for appliances and heating systems.

• Two hoses per pack: fit both tanks or keep one as a backup.
• Designed to work with common 2-stage auto changeover regulators.
• Accessible customer support for fitment or product questions.
• Used and reviewed by RV campers, Airstream owners, and full-timers.

Who is this for? RV owners, towable and motorhome occupants, and anyone using dual LP cylinder systems who need a reliable short pigtail hose that matches QCC-1 tank fittings and a 1/4" male inverted flare regulator inlet. Choose these GASPRO hoses when you want weather-resistant flexibility, brass fittings for longevity, and a convenient two-pack for both tanks or a spare replacement.
