Breaking Down the Features of **Marshall Excelsior MER425HSS-15P 15in. Pigtail High Flow Stainless**

Specifications

The Marshall Excelsior MER425HSS-15P 15in. Pigtail High Flow Stainless is a crucial component for any propane system needing reliable and safe gas delivery. It features a substantial 15-inch length, providing adequate reach for most common setups without introducing excessive slack. The primary material is a robust stainless steel braid, which is a significant upgrade in durability and protection over conventional rubber hoses. This braid offers excellent resistance to abrasion, UV exposure, and even minor impacts.

Crucially, this pigtail is designed for high-flow applications, boasting a capacity of 400,000 BTU/H, which is double the standard capacity. This is essential for appliances that demand a significant and consistent propane supply, like generators or larger heating units, ensuring they don’t suffer from fuel starvation. It incorporates an Excess Flow Safety Shut-Off feature, a critical safety mechanism that automatically reduces gas flow in the event of a broken gas line, significantly minimizing the risk of leaks and potential fires. The connection ends are equally well-specified: one side features a Female QCC Type 1 connection, the universal fitting for most modern propane tanks, while the other is a 1/4 inch inverted male flare, a standard size for connecting to regulators.

The unit is also compliant with both RVIA and NFPA 1192 standards, which are vital for anyone using propane in recreational vehicles or similar environments, ensuring it meets stringent safety regulations. The brass ferrules used to secure the braid provide a strong, corrosion-resistant connection point.
