Rigid Plastic Joiner 6mm ID x 8mm OD (5/16) x 50mm Long

Create clean, straight connections between compatible push-fit fittings with this 50mm rigid plastic joiner. Made from strong polypropylene, it is designed to connect two 8mm duotight or compatible John Guest fittings without requiring a flexible section of tubing.

Its rigid construction is particularly useful when mounting gas-system components to a wall or gas board, producing a straighter and tidier installation than a short length of flexible beverage line.

Key Features

Installation Notes

Push each end firmly into a compatible 8mm push-fit fitting until fully seated. The installed joiner should leave a small section exposed between the fittings, making it easier to operate the release collars when disassembly is required.

Confirm the pressure, temperature and chemical compatibility of every fitting in your system before use. Always depressurise gas and beverage systems before disconnecting components.
