This McAlpine blue blanking plug is designed to seal the unused appliance connection on a kitchen or utility waste trap, preventing leaks and smells from open outlets. Made from durable LDPE, it pushes into the internal spigot on McAlpine traps and fittings to cap off washing machine or dishwasher nozzles that are not in use. Using a blanking plug maintains the integrity of the trap seal and helps ensure efficient plunging if the sink becomes blocked. It is ideal when an appliance is removed, relocated or when a twin‑spigot trap is only serving one machine. Compact and easy to fit without tools, this plug is a simple, low‑cost way to tidy and secure domestic waste plumbing.

• Blue McAlpine blanking plug for sealing unused appliance outlets on traps and fittings.

• Fits internal spigots on washing machine and dishwasher waste trap nozzles.

• LDPE construction for a snug, durable and water‑tight push‑fit seal.

• Helps prevent leaks, odours and loss of trap seal when an appliance is disconnected.

• Quick, tool‑free installation – ideal for kitchen, utility or laundry room plumbing.
