Flame King Stainless Steel Braided Propane Pigtail Hose 12" 2-Pack — 1/4" Male NPT, Type 1 ACME, 80,000 BTU

Flame King’s 12-inch stainless steel braided propane pigtail is a 1/4" male NPT connector designed to link refillable cylinders to RV or trailer regulators safely and reliably. This stainless-steel braided pigtail hose comes as a convenient two-pack built for outdoor and mobile propane setups. Each 12-inch hose features a Type 1 ACME nut for attaching to common refillable tanks and a 1/4" male NPT outlet (note: not a flare fitting) for regulator or tee connections. Rated for up to 80,000 BTU/hr and a maximum working pressure of 250 PSI, the assembly also includes thermal and excess-flow safety elements to help reduce risks during abnormal events.

How does this pigtail connect to my RV propane system?

The pigtail attaches between a refillable propane cylinder and your RV or trailer regulator using the Type 1 ACME nut on the tank side and the 1/4" male NPT on the regulator side. It is intended to mate with standard regulator inlets or a 4-port brass tee for auxiliary supply hookups. Because the outlet is NPT, it will not fit flare-only fittings without an adapter.

• 12" length for compact, tidy connections
• Type 1 ACME nut fits common refillable cylinders (5–40 lb)
• 1/4" Male NPT for regulator or tee connections
• Not compatible with flare-only fittings without an adapter

Is this hose safe and rated for heavy-duty use?

Yes — the Flame King pigtail is built with a stainless steel braided outer layer and brass fittings to handle common RV and portable appliance loads. It carries an 80,000 BTU/hr rating and a 250 PSI maximum working pressure for robust performance. Integrated thermal protection and excess flow protection add passive safety features that act during high heat or sudden line ruptures.

• Rated 80,000 BTU/hr and 250 PSI max working pressure
• Stainless steel braid resists abrasion and weathering
• Thermal protection helps limit flow under fire conditions
• Excess flow protection helps stop gas if a break occurs

Which tanks and accessories work with these pigtails?

These hoses are compatible with refillable propane cylinders from 5 lb up through 40 lb that use a Type 1 ACME connection. On the appliance side they connect to regulators or a 4-port brass tee using the 1/4" male NPT thread. They are ideal as primary connectors or as auxiliary supply lines when adding a second source.

• Works with 5, 10, 20, 30, and 40 lb refillable propane tanks
• Connects to standard RV/trailer regulators and 4-port tees
• Good for primary or auxiliary LPG supply lines

How long will these hoses last and how should I maintain them?

With normal use and periodic inspection, the stainless braid and brass fittings provide long service life in outdoor and RV environments. Check connectors, fittings, and the braid regularly for wear, kinks, corrosion, or damage, and replace the hose if any compromise is found. Follow propane-safe practices: shut off valves when not in use, leak-test connections after installation, and store tanks upright.

• Inspect for kinks, abrasion, or damaged fittings before each trip
• Perform a soap-bubble or approved leak test after installation
• Replace immediately if damage, heavy corrosion, or leaks appear

Who is this for? If you own an RV, trailer, portable grill setup, or any propane-powered outdoor appliance that uses a regulator and refillable tanks, this Flame King 12" stainless braided pigtail two-pack is a practical replacement or spare. It suits users who want a compact connection with clear compatibility to Type 1 ACME tanks and 1/4" NPT regulator fittings, combined with passive safety features for everyday mobile and outdoor use.
