Caplugs PN12-3/4NPT hydraulic fitting is a protective threaded plug designed to shield 3/4-inch NPT hydraulic fittings during shipping, storage, and finishing processes. It is part of Caplugs’ PN12 hydraulic fitting protection lineup and helps prevent contamination of ports while safeguarding delicate threads from damage. Typical applications include masking off areas during finishing and use in low-pressure testing, contributing to longer hose life by keeping ports clean and protected. The part’s designation, PN12-3/4NPT, follows Caplugs’ catalog convention for 3/4" NPT fittings.
