Fit perfect. Another trick I've learned. Prob never have to use them again but well worth the money. ### ⭐⭐⭐⭐⭐ Great *by U***A on 28 November 2025* Perfect, did the job. Less spillage whilst installing trv valves. ### ⭐⭐⭐⭐ Decent snug fitting bungs *by K***Y on 4 December 2025* Great for using to bung feed and expansion tank pipes, enabling me to create a vacuum in heating system long enough to change a couple of radiator valves without too much water escaping and avoiding need to drain entire system. These bungs fit nice and snugly, so helped with the job… but you still have to be quick and know what you are doing to avoid a flood! A little bit pricey for two bits of moulded synthetic rubber. ## Frequently Bought Together - PLUMBING & HEATING BUNGS BY HEATLAB - Eliminate The Need To Drain A Full Central Heating System Down With These Plumbing Bungs, Tank Bung, Radiator Bung Kit - Essential Plumbing Tools And Equipment - Plumb Tub - SPI Radiator Draining Tub (Color May Vary) - 15mm & 22mm Grakob RCT3 Plastic Plumb Thumbs Radiator Capping Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/526037711-central-heating-system-plug-kit-eliminates-the-need-to-drain](https://www.desertcart.sk/products/526037711-central-heating-system-plug-kit-eliminates-the-need-to-drain) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-17*
