With valve depressor. R12 hi. Some older vehicles had the same fittings on both low & hi sides, so it's useful to have two adapters. - 90 deg adapter 1/4" M to 1/4" F. With valve depressor. The 90 deg ones are good for accessing ports where there is not a lot of clearance. - Straight adapter 1/4" M to 1/8" NPT M. With valve core. Could possibly be used on a gauge manifold. - Straight adapter 1/4" M to metric 9x1mm M. With valve core. No idea what this is used for. - Big adapter. 1/4 Male fitting is fine, female fitting is too small for 1/2" ACME, seems loose on 1/4" flare. Has valve depressor.
