The Trident 42421144 is a 12-foot high-pressure LP gas hose designed for connecting marine propane grills to onboard gas systems. It features a solid brass swivel fitting — 1"-20 female tee connection on one end and 1"-20 male on the other — with an integrated O-ring and check valve for a secure, leak-resistant connection.
Built to handle the demands of a marine environment, this hose is suited for permanent or semi-permanent grill installations where a high-pressure gas supply is required.
Parts Desk Insights
Best suited for boats with a dedicated onboard propane system feeding a fixed or rail-mounted grill. The tee-style swivel fitting allows this hose to branch off an existing gas line without interrupting supply to other appliances — ideal when running gas to both a grill and a cabin stove from a single tank. If you need a straight adapter hose without the tee configuration, see the Trident 40407-144 High Pressure Gas Grill 12' Adapter Hose. For low-pressure systems or complete connection kits, see the Trident Low Pressure Gas Grill Connection Kit with 10' Hose or the kit without hose.
