DMfit makes push-fit fittings and LLDPE tubing for beer, CO2 and drinking water. The fittings connect to the tubing without tools, and DMfit states that they are made from materials approved for contact with food and drinking water. Here you will find the full DMfit range at Brewshop: fittings from 5/32" to 1/2", adaptors to ball lock, BSP and NPTF, valves, filters and tubing.
How to choose the right DMfit fitting
Size: The fittings are sized by the outside diameter of the tubing, in inches or millimetres. 3/8" is common for beer, 5/16" for CO2 and 3/16" for restriction (anti-foam) tubing.
Adaptors: 1/4" FFL for ball lock, F 5/8" BSP for shanks and KeyKeg couplers, F 3/4" BSP for taps, and NPTF threads.
The line: union connectors, reducers, a Y-splitter, a three-way divider and bulkhead connectors for walls and cabinets.
Control: shut-off valves, a flow control valve and 100 mesh filters that catch particles in the line.
LLDPE tubing – 3/16" restriction tubing in black and natural, and tubing in 5/16", 3/8" and 4 mm.
Spare collets – in 3/16", 5/16", 3/8" and 1/2", fitting both DMfit and John Guest.

Frequently asked questions about DMfit
Is DMfit compatible with John Guest?
Yes, in the same inch sizes. You can use DMfit fittings on John Guest tubing and vice versa, and mix fittings from both in the same line.
Is DMfit approved for beer and drinking water?
DMfit states that the fittings are made from FDA-approved materials, that they are suitable for contact with food and drinking water under NSF-51 and NSF-61, and that they are produced under a quality system registered to ISO 9001 and ISO 14001.
Which DMfit fitting do I need for 3/16" restriction tubing?
From a 3/8" line, use the 3/8" – 3/16" reducer, and from 5/16" use the 5/16" – 3/16" reducer. The 1/4" – 3/16" union connector joins 3/16" tubing to 1/4".
What is a DMfit Power fitting?
A Power fitting has a nut that can be tightened around the tubing so the fitting grips harder. The DMfit Power Union Connector 3/8" x 5/16" is used on the Lindr AS-110, among others.
