The Russell 1/2 in Allen-socket pipe plug is a precision-machined internal-wrenching NPT plug in black anodized 6061-T6 aluminum. Sold in pairs, these plugs deliver a positive seal at maximum operating pressures and are used to close unused pipe-thread ports on oil pumps, fuel pumps and filters. The black finish coordinates with other Russell fittings for a finished appearance.
