Universal Rubber Radiator Drain Plug – Pack of 2 Stepped Bungs
A reliable solution for anyone who works on radiators, water‑cooling systems or any plumbing line that uses 5 mm‑22 mm tubing. These stepped rubber bungs are engineered to seal out sludge, water and oil drips while you disassemble or service a radiator, hose or tube.
Why they work
– Easy hand‑install – push the plug in and twist; no wrenches or special tools needed.
– Strong, reusable seal – the octagonal base grips the pipe firmly and can be removed and re‑installed countless times without losing elasticity.
– Wide temperature range – stays flexible from –25 °C up to +90 °C, so it handles cold‑start coolant as well as hot‑run water.
