NPT 1/2" Stainless Steel Hex Socket Plug (SS316L) | PLG-N08-SS316L

Seal any NPT 1/2" female port with a flush hex socket plug. The PLG-N08-SS316L is a Stainless Steel 316L male NPT pipe plug with a 3/8" hex (Allen key) socket, so it sits close to the port face and installs where a wrench will not fit. It closes our matching WB-N08 weld bung and any standard NPT 1/2" female thread on tanks, manifolds, pumps, gearboxes and fabricated fittings. It also seals the 1/2" NPT step inside the ports of our AdaptorMount WYE 45° hubs.

NPT 1/2" male, 14 TPI, tapered 1:16 per ASME B1.20.1, right hand thread. Length 0.562", 3/8" hex socket 0.312" deep. 45° chamfer on both ends. Machined from Stainless Steel 316L bar with 3.1 mill certificate, passivated, and laser engraved with the AdaptorMount logo, thread size and material. 316L low carbon stainless resists corrosion in water, chemical and marine service. Seal with PTFE tape or an anaerobic pipe sealant.
