Copper M-Press Straight Union MI
Product details
A copper M-press straight union MI joins copper tube to a male threaded connection through a union, so the joint can be undone later without cutting the pipe. Use it on pumps, valves, appliances and anything that may need taking out for service. Sizes are 15mm x 1/2", 22mm x 3/4" and 28mm x 1".
Why installers use it
- Undo and remake: break the union to remove equipment, then reconnect.
- Male thread: screws into a female port.
- Press end: flame-free on the tube side with an M-profile jaw.
- Bags of 5: or a box. Our supplier does not split packs.

Questions
Why use a union instead of a male adaptor?
A union can be undone without turning the tube, so you can take out a pump or appliance and put it back.
What is the smallest pack?
A bag of 5 in every size. Packs are not split.
