Description
This bulkhead connector is designed for routing imperial beer, beverage or gas lines through walls, panels or partitions. It provides a secure and professional method of carrying pipework between cellar areas, bar counters or equipment enclosures. The threaded bulkhead body allows the fitting to be mounted through a drilled panel and secured in place, creating a stable pass-through point for drinks dispense pipework. This helps protect tubing from abrasion while maintaining a clean and organised installation.
Manufactured from rigid grey acetal copolymer with a nitrile O-ring, the connector delivers an airtight push-fit seal on both sides. The secure collet design holds tubing firmly without deforming it or restricting flow, helping maintain stable pressure and consistent pour performance. Suitable for potable liquids, food grade liquids and inert gases, the fitting can be used in accordance with the British Beer and Pub Association Code of Practice on N2, CO2 and mixed gas dispense systems. It also supports air, pneumatic and vacuum applications up to 16 bar for air.
Fully demountable, the bulkhead connector allows tubing to be disconnected and reconnected without tools, simplifying maintenance and system modifications in busy pub environments.
