Advanced 9J-Cap JIC female 37° flare sealing cap. Features precision internal UN/UNF straight threads, a machined 37° female cone seat, and a heavy-duty hexagonal solid body. Threaded directly onto external JIC male 37° flare fittings to deliver airtight metal-to-metal dry shutoff, contaminant exclusion, and burst-proof reliability in SAE J514 / ISO 8434-2 high-pressure hydraulic circuits.
The 9J-CAP Series is a critical line-terminating component specifically engineered for sealing off male threaded ports and exposed line ends within SAE J514 / ISO 8434-2 standard hydraulic systems. Designed to thread directly onto JIC male 37° flare fittings, this heavy-duty cap incorporates an internal precision-machined 37° female cone seat that mates firmly against the male nose cone. It provides a secure, permanent or temporary positive dry seal, safeguarding fluid circuits against external contamination and high-pressure fluid loss during line isolation, transport, or system maintenance.
With optional zinc-nickel alloy surface treatment available to significantly extend service life, this hydraulic JIC female flare cap ensures maximum longevity, structural safety, and leak-proof performance for heavy-duty industrial fluid power networks.
