NPT 1/4" Super Duplex 2507 Hex Socket Plug (SD2507) | PLG-N04-SD2507

Seal any NPT 1/4" female port with a flush hex socket plug. The PLG-N04-SD2507 is a Super Duplex Stainless Steel 2507 male NPT pipe plug with a 1/4" 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-N04 weld bung and any standard NPT 1/4" female thread on tanks, manifolds, pumps, gearboxes and fabricated fittings.

NPT 1/4" male, 18 TPI, tapered 1:16 per ASME B1.20.1, right hand thread. Length 0.438", 1/4" hex socket 0.220" deep. 45° chamfer on both ends. Machined from Super Duplex Stainless Steel 2507 bar with 3.1 mill certificate, passivated, and laser engraved with the AdaptorMount logo, thread size and material. Super Duplex 2507 (UNS S32750, PREN 40 min) is the upgrade for seawater, chlorides, offshore and other severe service, with roughly twice the strength of 316L. Seal with PTFE tape or an anaerobic pipe sealant.
