INSTALLATION & USE
Connection Process
- Ensure tubing is cut square and clean, with no burrs or deformation at the cut edge
- Push the fitting fully onto the pipe until it seats completely against the internal stop
- Turn the male connector onto the BSPT female thread until hand-tight, ensuring proper seal engagement
- To disconnect, turn the nut to unlock, push the collet toward the fitting body, and pull the pipe free
COMPATIBILITY
Suitable Applications
This John Guest acetal male connector is engineered for use with potable water systems, reverse osmosis installations, refrigerator lines, beverage dispensing equipment, and pneumatic applications. The food-grade nitrile O-ring and acetal construction meet standards for contact with drinking water and foodstuffs. Compatible with CO2 systems, compressed air lines, and vacuum applications. Threads conform to British Standard Pipe Thread (BSPT) specifications—note that BSPT sizing differs from actual measured diameter (e.g., 1/4" BSPT measures approximately 0.518" on a ruler).
🔧 Pro Tip: BSPT threads are tapered and measure larger than their nominal size. Always verify actual thread diameter against the reference table before ordering—a 1/4" BSPT fitting measures roughly 0.518" in diameter, not 0.25". Use PTFE tape on male threads for optimal seal when connecting to female BSPT ports.
