Grey nuts for the dos units

[kac0143]

I lost the four grey threaded nuts that go on the dos units and hold the 1/4 inch hoses. Apex sale the head assembly but not the nut by itself. Anywhere I can get just the nuts? Thanks

The John Guest connectors are definitely better than stock pressure fit caps.
Less likely to leak air, although they still can do so at times.
Plumber's tape on the threads of each DOS head will reduce the chance of this happening.

Do the mod! Mines been rock solid! I used a fresh razor to cut off the “nipples” where the soft tubing would go. Then i did 3 wraps of teflon tape. Screwed the fittings on and it works amazing!
