Description
Square head plugs blank female ports when high seating force and a square drive are preferred on heavy equipment. FerruleX SS304/SS316 stainless steel pipe fittings cover common plug threads for process valves and large blocks. The square head takes a wrench securely when hex heads round off under abuse. Permanent or semi-permanent blanks are the usual duty. Quote thread size to FerruleX on a factory RFQ; stocked plugs ship fast. Check guard clearance; square heads stand proud of socket plugs on mobile equipment. 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. Brand FerruleX; Material SS304 / SS316; Type Square head plug; Threads NPT / G / Metric; Order mode Factory RFQ.
Square heads stick out farther than socket plugs — check guard clearance on mobile equipment. Anti-seize on stainless threads reduces galling when the plug may be removed years later. FerruleX can supply drilled and wired square heads when vibration lockwire is on the drawing. Square head for high seating force. SS304 / SS316. Permanent or semi-permanent port blanks.
