The John Guest Speedfit Acetal Straight Adaptor (PM011514E) is a professional-grade male BSP to pushfit connector specifically designed for installers and engineers working in food, beverage, and water purification systems. Its primary benefit is the combination of rapid installation and a reliable, leak-proof seal, though it requires precise tube cutting to ensure peak performance. Engineered from non-toxic acetal copolymer, this adaptor offers high chemical resistance and durability in demanding industrial and domestic applications.

Yes, it complies with WRAS and ANSI/NSF-61 standards, making it fully suitable for potable water systems.
It is designed for use with plastic tubing such as LLDPE or semi-rigid nylon. Using metal tubing may damage the internal O-ring seal.
No, it is a tool-free fitting. You only need to push the collet inward to release the locking teeth.
Performance ratings vary by tube type and temperature; please refer to the specific John Guest technical data sheet for your tubing size.
Yes, the fitting is designed to be disassembled and reassembled multiple times without losing its sealing integrity.
Remove the tube, check that the end is cut square and is free of scratches or burrs, then re-insert firmly.
Ensure the collet is pushed in evenly and uniformly around the circumference of the tube before pulling.
Check if the connection was cross-threaded during installation; apply PTFE tape to the male threads if leakage persists.
To install, ensure the tube end is cut cleanly and squarely using a plastic pipe cutter. Insert the tube firmly into the pushfit end until you feel it pass the O-ring and seat against the internal tube stop. When attaching the male BSP end to your threaded port, use appropriate thread seal tape if required by the application. For maintenance, keep the fitting clean of debris. If the fitting must be disconnected, depress the collet evenly while pulling the tube out. Avoid using harsh chemical cleaners on the exterior; simple warm water or a damp cloth is sufficient.
