John Guest tap adaptor for 1/4-inch tube outside diameter and a 1/2-inch female BSP tap connection. The two inch sizes refer to different connection types; confirm the actual model, tube and mating thread before ordering.

This is a small-bore tubing adaptor, not a waste-pipe reducer or a general 15mm Speedfit plumbing connector. Check the intended fluid, operating conditions and supplied sealing arrangement for the exact part.

Match the adaptor and tubing

The manufacturer's BSP tap-adaptor range lists CI320814S for 1/4-inch tube and a 1/2-inch female BSP tap connection. Confirm the supplied reference and revision. A similar-looking tap adaptor with a different thread or suffix may have different limits.

Use the exact model's requirements for compatible tube material, tube support or liners, thread and seal. Do not apply generic Speedfit plumbing-pipe inserts to every small-bore tube. Confirm the actual nut, washer and supplied quantity rather than assuming pack contents.

Pressure and temperature limits must be checked together for the intended fluid and current model. Do not assume a general heating, gas, air or vacuum rating, a universal 16-bar limit, or a complete installation approval from the product name.

See the manufacturer's BSP tap-adaptor range for model-specific documentation. No installation or thread-sealing procedure is provided here.
