HOLO-KROME 12008 3/8"-18 PTF 平頭鎖緊壓力塞 | 7/8" 錐度 | 合金鋼熱處理黑氧化物 (100 個/包)

Needed plugs for a hydraulic manifold repair, and these PTF taper threads sealed perfectly the first time. The flush fit is clean and the black oxide coating looks quality.

The hex socket drive makes these plugs easy to install with a standard Allen key, and the taper threads sealed my hydraulic test port perfectly on the first try. I’ve bought cheaper plugs before that leaked, but these are worth every penny.

The black oxide finish on these plugs looks clean and professional once installed. I used a dozen on a hydraulic manifold and every one sealed tight with no leaks first try.
