Description
Overview
The Tenob Drain Plug (ID RWB0635) is a large, marine-grade bung for livebait tanks, bilges and general drainage. It delivers a 35 mm internal flow and installs into a 40 mm cut-out, so solids pass more freely. The UV-stable nylon body and neoprene O-ring help maintain a reliable seal, while the retainer ring preserves full-bore throughput even under constant washdown. Because the assembly is compact and lightweight, installation is straightforward and service access remains easy over the life of the fitting.
Features
- Full-flow retainer ring for minimal restriction and fast draining
- Neoprene O-ring for repeatable watertight closure
- UV-stable marine nylon body designed for durability
- Four countersunk mounting holes for secure, flush fastening

Compatibility and Fitment
This Tenob drain plug suits flat panels or tank walls where a 40 mm hole can be cut. Position the flange so the 35 mm bore is unobstructed, then fasten using corrosion-resistant screws. Tighten evenly to seat the O-ring; however, avoid over-torquing to prevent stress in the nylon. After installation, check for seepage and re-snug fasteners after initial use.
Compliance and Safety
Use stainless fasteners compatible with marine environments. Inspect the O-ring regularly and replace if hardened or damaged. Because plastics can creep under sustained load, re-check torque seasonally. In addition, confirm your installation practice aligns with relevant small-craft fitting standards for through-hull and drain hardware.
Marine Applications
Typical uses include livebait wells, fish boxes, aft deck drains and bilge service points. The generous 35 mm flow path reduces clogging, therefore maintenance time is reduced and drainage efficiency improves. Moreover, the lightweight nylon body helps minimise galvanic issues compared with metallic alternatives.
