Q 1. What pipe size does the CASKIT328 use?

A. The CASKIT328 uses Ø28mm rigid nylon pipe, with six 3-metre lengths included in the kit.

Q 2. How many drop points does this kit support?

A. This is a 3-drop system covering 18 metres of ring main, providing three outlet positions around your workshop.

Q 3. Do I need to thread the pipes or use solvents during installation?

A. No. The John Guest® CAS push-action fittings require no thread preparation and no solvents - pipes simply push into the fittings.

Q 4. What thread standard is the straight adaptor in this kit?

A. One straight adaptor is included, sized Ø28mm x 1" BSP.

Q 5. What wall box size is supplied with the CASKIT328?

A. Three 3/4" wall boxes (model CAS34WB) are included.

Q 6. Can I reconfigure the pipework layout after installation?

A. Yes. The push-fit fittings can be disassembled and reconfigured quickly, allowing you to adapt the system as your workshop changes.

Q 7. Is the CASKIT328 suitable for uses other than compressed air?

A. Yes. The CAS system can also be used for drinking water movement.

Q 8. How does the 28mm CASKIT328 differ from the 15mm CASKIT315?

A. The CASKIT328 uses Ø28mm pipe and fittings compared to Ø15mm in the CASKIT315, making it suited to higher-flow applications. The straight adaptor thread differs accordingly (1" BSP versus 3/4" BSPT).

Q 9. Where can I find full specifications for individual components in the kit?

A. Please refer to the individual model numbers listed in the kit contents for full specifications, or contact Parts for Machines for confirmation.

A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging.
