The T-H Marine Drain Plug is a screw-type drain plug constructed of black polypropylene and features a chemically inert "O" ring for positive sealing. Strong threads maintain sealing under high vibration conditions and its special design prevents cross-threading. This drain plug mounts in a 1" diameter hole with two #8 countersunk stainless steel screws. The backside of the mounting flange has a groove to hold sealant for positive waterproof mounting and the mounting flange is approximately 1 1/2" x 2".
The T-H Marine Drain Plug is ideal for boat transoms, fish wells, bait tanks, water tanks, coolers, ice chests, or almost any application where a positive sealing drain plug is required. This drain plug is not only quick and simple to install, but it also provides a definite cost advantage over outdated, leaking flared-type drain tubes.
