Air Fitting And Hose Coupler Sort Block
A 148 x 118 mm tray with 11 thread-down cups for loose brass fittings. There are four 15 mm cups for 1/4" NPT plugs and couplers (thread OD 13.7 mm), four 18.5 mm cups for 3/8" NPT (17.1 mm) and three 28 mm cups for 3/4" garden-hose GHT fittings (about 26.5 mm). The bores are oversize so slightly different brands still fit. Each fitting stands on its threads with the hex body sitting on a chamfered rim, so the drawer full of mixed couplers becomes one tray you can read at a glance.
