Is the JIC Plug with Stainless Steel UNF Thread, Type VKA compatible with 37° female ports and rated for high‑pressure hydraulic systems?

Yes. The JIC Plug with Stainless Steel UNF Thread, Type VKA is specifically designed for use with 37° female ports (internal 37° cone) and provides a secure, leak‑free seal when fitted correctly. Manufactured from AISI 316 stainless steel, it offers excellent corrosion resistance and chemical compatibility for hydraulic, pneumatic and industrial fluid systems. The description also notes it is engineered for high pressure — its robust construction and precise UNF threading deliver durable performance and reliable sealing in demanding, high‑pressure hydraulic applications.

Does the JIC Plug with Stainless Steel UNF Thread, Type VKA require any special torque or installation procedure to ensure a reliable 37° cone seal under high‑pressure conditions?

Yes. The JIC Plug with Stainless Steel UNF Thread, Type VKA requires correct installation to ensure a reliable 37° cone seal under high‑pressure conditions: - Clean mating surfaces and threads of debris, burrs, and contamination to prevent misalignment and impaired sealing. - Inspect the 37° cone seat and plug for damage or nicks; any imperfection can compromise a metal‑to‑metal seal at high pressure. - Use correct thread engagement: hand‑start the plug to avoid cross‑threading, then tighten with a calibrated wrench. - Apply torque consistent with component size and material: while the product description does not specify a value, use manufacturer torque charts for AISI 316 UNF fittings or industry standards for JIC fittings of the same size. Over‑torquing can deform the cone and under‑torquing can leak. - For high‑pressure service, prefer a torque wrench and incremental tightening (hand tight + controlled final torque). - If required by system practice, use a thread lubricant or anti‑seize compatible with AISI 316 and system fluid to achieve consistent torque readings; avoid sealants that interfere with the metal cone seal. - After installation, perform a hydrostatic or pressure test at or above operating pressure to verify leak‑free sealing. If you need, provide the plug size and system pressure and I can recommend a specific torque value and step‑by‑step procedure.
