FAQs
What size tubing does this adapter set work with?
This adapter set is designed to connect standard 1/4 inch (0.25 inch) diameter water filter tubing.
Do I need any special tools for installation?
Basic tools like a wrench (for tightening the brass fittings) and a tubing cutter are recommended. PTFE tape might also be necessary for threaded connections.
What does the set contain?
The set includes 2 x 3/4" to 3/4" Brass Hex Nipple fittings and 2 x 3/4" DMFIT Female to 1/4" Pushfit fittings.
Can I use this with plastic tubing?
Yes, this adapter set is compatible with standard plastic water filter tubing commonly used in filtration systems.
What if the threaded connection leaks?
You likely need to apply PTFE tape or pipe dope to the male threads before screwing in the brass nipple. Ensure it is tightened sufficiently.
How do I remove the 1/4" tubing from the push-fit connector?
To release the tubing, firmly push the collar ring on the push-fit connector inwards while simultaneously pulling the tubing out.
Is this adapter suitable for high-pressure systems?
The brass fittings are durable, and push-fit connectors are generally rated for typical household water pressure. However, always ensure your entire system is rated appropriately and connections are secure.
Troubleshooting
Leak at the 3/4" threaded connection
Ensure PTFE tape (or pipe dope) is applied correctly to the male threads being inserted into the fitting. Tighten the fitting securely with a wrench, but avoid over-tightening which could damage the threads.
1/4" tubing will not insert into push-fit connector
Ensure the tubing end is cut cleanly and squarely. Remove any burrs from the end of the tubing. Push the tubing in firmly until it is fully seated.
Leak at the 1/4" push-fit connection
Remove the tubing and re-insert it, ensuring it is pushed in completely. Check the end of the tubing for any damage or debris. If the tubing is old or deformed, it may need to be trimmed and re-inserted.
Water flow seems restricted
Verify that the 1/4" tubing is fully seated in the push-fit connector and that the 3/4" threaded connection is properly sealed. Ensure no kinks are present in the 1/4" tubing.

Setup, Compatibility & Care
Setup:
Identify the 3/4" female threads on your water filter system or housing.
Screw one of the 3/4" brass hex nipple fittings into the female thread. Hand-tighten first, then use a wrench for a snug fit. *Note: PTFE tape may be required on the threads for a secure, leak-proof seal, especially if the existing threads are not perfectly smooth or are designed for tapered threads.*
Attach a 3/4" DMFIT female to 1/4" push-fit adapter onto the open end of the brass nipple.
Cut your 1/4" water filter tubing cleanly to the desired length.
Insert the end of the 1/4" tubing firmly into the push-fit opening of the DMFIT adapter until it seats properly.
Repeat for any additional connections needed.
Compatibility:
Designed for systems with 3/4" female threaded ports.
Specifically compatible with standard 1/4" (0.25 inch) diameter water filter tubing.
Works with most standard water filter housings and under-sink filtration systems.
Care:
Clean fittings with a damp cloth if necessary. Avoid abrasive cleaners.
Periodically check connections for leaks, especially after initial installation or if the system experiences pressure fluctuations.
Ensure tubing is properly seated in the push-fit connectors.
