Parts Desk Insights
Best Use Case: This plug is the go-to solution for sealing 1/2" NPT ports on engine blocks, raw water strainers, and marine plumbing manifolds — especially during winterization or when reconfiguring a plumbing circuit. The bulk format is well-suited for service departments that regularly stock brass fittings.
Pairs well with the Seachoice Garboard Drain Plug (1/2" Pipe) and the Brass Baitwell Plug 5/8" for complete livewell and drain fitting setups. Also consider the Seachoice Brass Fuel Tank Elbow 1/4" NPT for fuel system plumbing work.
