Universal plumbing & heating bungs - eliminate the need for draining an open heating or water system down.

 ✅ Unlike traditional rubber bungs, our bungs are made of hard silicone. This material is more grippy, making them easier and safer to use while bunging a tank, as there is less chance of them falling out.                                                            

✅ Two sizes in one: Our bungs come in two sizes - 15mm and 22mm - making them more versatile than other bungs that typically come in just one size.

✅ Durable and long-lasting: The hard silicone material makes our bungs more durable and long-lasting compared to traditional rubber bungs.
