Marshall Excelsior 15" Propane Pigtail | QCC Type 1 | Std or Hi-Cap

Connect the cylinder to the regulator with a Marshall Excelsior 15" Propane Pigtail. The QCC Type 1 hand-wheel connector threads onto the tank valve and the 1/4" male end goes to the regulator inlet. Choose standard capacity, or high-capacity for rigs with multiple large appliances.

⚠️ Check the Regulator Inlet

• MER426-15 — 200,000 BTU, 1/4" MNPT end, thermal protection
• MER426H-15 — 400,000 BTU high flow, 1/4" male inverted flare end

The two use different regulator-side threads. Match yours before ordering.

⚠️ Propane Safety

Use only fittings and hoses rated for LP gas, check every connection with leak-detection solution after installation, and never use flame to test. If you're not comfortable working on gas lines, have an RV technician install this part.
