This connector is manufactured using non-toxic acetal copolymer, meeting the requirements of the US FDA, WRAS, ANSI/NSF-51, 61 and SK Zert. They are commonly used in food/beverage, pneumatic systems and water purification. Tube diameter: 5/16" Pushfit + 5/16" Pushfit Superior flow characteristics Quick and convenient assembly Can be assembled and disassembled repeatedly Suitable to be used with water, food, air, gases, vacuum and liquids.
This guide is for users of the John Guest PM0308S, a 5/16" pushfit to pushfit equal elbow connector. Its key benefit is providing a quick, reliable, and reusable connection for various fluid systems. A potential caveat is ensuring compatibility with the specific tubing size and fluid type being used. The connector is manufactured from non-toxic acetal copolymer and offers superior flow characteristics for efficient system operation.

FAQs
What is the maximum pressure this connector can handle?
While specific pressure ratings vary by application, these connectors are generally suitable for low to medium pressure applications typically found in domestic water, pneumatic, and food/beverage systems. Consult John Guest for detailed specifications if operating near maximum limits.
Can I use this connector with different sizes of tubing?
No, this specific model (PM0308S) is designed exclusively for 5/16" outside diameter tubing on both pushfit connections.
How do I disconnect the tubing from the connector?
To disconnect, push the tube firmly into the connector body while simultaneously pulling the tube outwards. Some models may have a specific release button or collar; ensure it is depressed before pulling the tube.
Is this connector suitable for high-temperature applications?
The acetal copolymer material has a working temperature range. It is generally suitable for ambient to moderately warm fluids. For very high temperatures, consult John Guest's product specifications or alternative material options.
Can I use this with compressed air?
Yes, the John Guest PM range, including this elbow connector, is suitable for use with compressed air systems, provided the pressure and temperature are within the operational limits of the connector.
What does 'Equal Elbow' mean?
'Equal' means both pushfit connections are the same size (5/16" in this case), and 'Elbow' indicates it creates a 90-degree change in direction for the tubing.
Troubleshooting
Connector leaks after installation
Ensure the 5/16" tubing is cut cleanly and squarely. Check for any dirt or debris on the tubing end or inside the connector port. Try re-seating the tubing firmly.
Tubing is difficult to insert
Confirm you are using 5/16" outer diameter tubing. Ensure the tubing end is not deformed or kinked. Slightly warming the tubing end in warm water may help, but avoid excessive heat.
Connector does not hold tubing securely
Inspect the internal gripping collet for damage or wear. Ensure the tubing is pushed in fully until it locks. If the collet appears damaged, the connector may need replacement.
Pros and Cons
Pros
Easy tool-free assembly and disassembly
High compatibility with a wide range of fluids and gases
Durable construction from non-toxic materials
Ensures a secure and leak-free connection
Compact design for efficient space utilization
Cons
Limited to 5/16" tubing size
Requires clean and undamaged tubing ends for proper sealing
Not suitable for high-pressure applications beyond its specified limits
Setup, Compatibility & Care
Setup:
Ensure the tubing end is cut cleanly and squarely.
Remove any burrs or sharp edges from the tubing.
Push the 5/16" tubing firmly into the connector port until it is fully seated. You will feel a slight resistance as it seals.
Repeat for the second port.
Compatibility:
Tubing: Primarily designed for 5/16" outside diameter tubing. Ensure your tubing material is compatible with the fluid being conveyed and the operating temperature range.
Fluids: Suitable for potable water, food-grade liquids, air, gases, and vacuum. Consult John Guest for specific chemical compatibility if needed.
Environment: Suitable for indoor use in ambient conditions. Avoid extreme temperatures or direct sunlight for prolonged periods.
Care:
Cleaning: If cleaning is necessary, disconnect the tubing and wipe the exterior with a damp cloth. Avoid using abrasive cleaners or solvents.
Maintenance: Periodically check connections for security, especially if the system experiences vibrations or pressure fluctuations. The connectors are designed for repeated use, but ensure the internal seals remain free from debris.
