Milton 776 1/4" MNPT Male A-Style Coupler - Pack of 10 - Ideal for Air Compressor, Pneumatic Tools & Industrial Applications

Bought this (and some other Milton units) to standardize my workshop on a single quality connector. I had one out of box failure (leaked at the factory joint) out of about 25 units. Itwas promptly replaced by the seller free of charge, very pleased.I orders up various quantities of the S775 (ends of hoses or hose reels and tools with 1/4" NPT male), S776 (tools with 1/4" NPT female), S213 (5 piece set of the 75 & 76, plus the male A series ends you need for loose hoses), S745 (used to make a conversion hose so I can borrow a friends tools that use the M style connectors). All interconnect nicely, and seal beautifully. The real test is time and use, so maybe in 6 months after I drag them around the shop can comment on longevity.One thing that I found an improvement over the cheapo crap ones, I can snap a tool in one handed, without having to retract the collar to insert. Nice! Would highly recommend these to replace the cheap ones that are bought at your local import tool store which all leak and get sloppy very quickly.
