Description
Hex socket plugs seal female NPT, G or metric ports with an internal hex drive when external wrench clearance is gone. FerruleX stainless steel pipe fittings in SS304/SS316 drop into manifolds and valve bodies that sit flush to a wall. The recessed drive keeps the plug face tidy on compact blocks. Thread size drives the RFQ — there is no tube OD on this part. Ask FerruleX for the thread code and alloy; stocked plugs ship fast on factory quotes. Apply anti-gall compound appropriate to the media when seating stainless into stainless. Instrument plugs typically run 1/8–1 inch NPT with G and metric options; pressure follows the port and fitting rating rather than a plug class of its own, so it is confirmed on the RFQ. Values are class-typical references for this configuration; thread standard, size and pressure class are confirmed on the RFQ.
Use the correct hex key length so you do not round the socket under high seating force. Apply thread sealant appropriate to the media; stainless dry threads can gall if you force them. FerruleX can supply plugs with nylon tip options when a soft seal face is on the drawing.
