This adapter 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. Diameter: 1/4" NPTF Female x 1/4" Pushfit. Quick and convenient assembly. Unique oval collet design. Can be used with water, food, air, gases, vacuum and liquids. Can be assembled and disassembled repeatedly. Operating pressure (max.): 10 bar. Material: Acetal copolymer.
This DMFit adapter is designed for professionals and DIY enthusiasts working with fluid or pneumatic systems. Its key benefit is providing a quick, reliable, and reusable connection between a 1/4" NPTF female port and a 1/4" pushfit tube, simplifying assembly and maintenance. A potential caveat is its maximum operating pressure of 10 bar, which may not suit extremely high-pressure applications. Key features include its non-toxic acetal copolymer construction, compliance with various safety standards, and a unique oval collet design for easy disconnection.

Extended Product Information
FAQs
What type of tubing can be used with this adapter?
This adapter is designed for 1/4" Outer Diameter (OD) flexible tubing. Ensure the tubing material is compatible with the fluid being transported and the operating conditions.
Is this adapter suitable for drinking water systems?
Yes, the adapter is manufactured from non-toxic acetal copolymer and meets US FDA, WRAS, ANSI/NSF-51, 61 standards, making it safe for potable water applications.
What is the maximum pressure rating?
The adapter can operate reliably up to a maximum pressure of 10 bar (approximately 145 psi).
Can I reuse this adapter after disconnecting?
Yes, the unique oval collet design allows for repeated assembly and disassembly without compromising the seal.
Do I need special tools to install this adapter?
No, installation is quick and convenient. Standard tools may be needed for the NPTF thread connection (like a wrench), but the pushfit connection requires no special tools.
What media can be used with this adapter?
It is suitable for water, food, air, gases, vacuum, and liquids. Always confirm material compatibility for specific chemicals.
How do I ensure a leak-free connection on the NPTF side?
It is recommended to use a suitable thread sealant, such as PTFE tape or liquid pipe sealant, on the male threads of the component connecting to the NPTF female port.
Troubleshooting
Leak at NPTF thread connection
Ensure thread sealant (PTFE tape or liquid) was properly applied. Check that the male thread is clean and undamaged. Tighten the connection appropriately, but do not overtighten.
Tubing does not lock into pushfit end
Verify that the tubing is 1/4" OD and is inserted fully and squarely. Ensure the tube end is cut cleanly with no burrs. Check if the collet is obstructed or damaged.
Tubing easily pulls out of pushfit end
The collet may not be gripping the tube. Ensure the tube is fully inserted. The collet or tube end might be worn or damaged. Disassemble and reassemble, ensuring the tube is seated correctly.
Difficulty disconnecting tubing
Ensure the oval collet is being pushed inwards towards the adapter body completely before pulling the tube. Check for any debris or damage around the collet mechanism.
Pros and Cons
Pros
Quick and easy installation using push-to-connect technology.
Suitable for a wide range of applications including food and beverage.
Can be disconnected and reconnected multiple times without compromising seal integrity.
Made from safe, non-toxic materials compliant with major health and safety standards.
Compact design for use in space-constrained systems.
Cons
Limited to a maximum operating pressure of 10 bar.
Requires a smooth, clean-cut tube end for proper pushfit connection.
NPTF threads require thread sealant for optimal leak prevention.
Not designed for extremely high-temperature applications.
Setup, Compatibility & Care
Setup:
Thread Preparation: Ensure the 1/4" NPTF female port is clean. Apply a suitable thread sealant (e.g., PTFE tape or liquid sealant) to the male thread it will connect to, or directly to the female port threads if connecting to a male fitting. Thread the adapter in securely.
Pushfit Connection: Cut the 1/4" OD tubing cleanly and squarely. Insert the tube end straight into the pushfit collet until it is fully seated. A gentle push should suffice.
Disconnection: To release the tubing, push the oval collet inwards towards the adapter body while simultaneously pulling the tube outwards. Ensure the collet is fully depressed before attempting to remove the tube.
Compatibility:
Thread Standard: Compatible with standard 1/4" NPTF (National Pipe Taper Fuel) female threads.
Tubing: Designed for use with 1/4" OD (Outer Diameter) flexible tubing suitable for the intended media (water, air, food, etc.).
Media: Can be used with air, gases, vacuum, potable water, food products, and many common liquids. Always verify material compatibility for specific chemicals.
Pressure: Maximum recommended operating pressure is 10 bar (approximately 145 psi).
Care:
Clean the exterior of the adapter with a damp cloth. Avoid abrasive cleaners or solvents that could degrade the acetal copolymer.
Periodically check connections for any signs of wear or damage, especially the collet mechanism and the seal area.
Ensure the system is depressurized before making or breaking connections.
