Is the JIC plug with UNF GZ in carbon steel, type ROV compatible with hoses and fittings sealing on the external 37Â° cone?

Yes. The JIC plug with UNF GZ in carbon steel, type ROV (JIC 37Â° plug with external UNF thread, sealing on the external 37Â° cone) is compatible with hoses and fittings that seal on an external 37Â° cone. The plug is specifically designed to mate with standard JIC/SAE 37Â° flared fittings: its external 37Â° cone face provides the metal-to-metal sealing surface required by those fittings. Ensure matching thread size and pitch (UNF), correct torque, and material/finish compatibility (carbon steel, galvanized) to prevent galling and corrosion; use appropriate sealing practices (clean mating surfaces, apply anti-seize if recommended).

Does the JIC plug with UNF GZ in carbon steel, type ROV seal reliably on external 37Â° cone fittings?

Yes. The JIC plug with UNF GZ in carbon steel, type ROV Format (JIC 37Â° plug with external UNF thread, sealing on the external 37Â° cone) will reliably seal on external 37Â° cone fittings when manufactured and installed correctly. Carbon steel, galvanized, provides adequate strength and corrosion resistance for typical hydraulic applications; the 37Â° cone metal-to-metal contact created by the plugâs external cone and the mating female fitting forms a robust, leak-tight seal. Reliable sealing depends on correct thread engagement, proper torque, undamaged cone faces, and compatible surface finish and tolerances. Avoid using damaged or mismatched fittings, and follow manufacturer torque/specifications to ensure consistent sealing performance.

Can the JIC plug with UNF GZ in carbon steel, type ROV be used with fittings that seal on the external 37Â° cone?

No. The JIC plug with UNF GZ in carbon steel, type ROV Format is designed to seal on its external 37Â° cone against a flat or complementary internal cone surface. It will not properly seal with fittings that are designed to seal on the external 37Â° cone (i.e., fittings that have an external cone mating surface), because both mating faces would present external cones and no proper metal-to-metal cone contact will form. Using them together risks leakage and potential damage to sealing surfaces. For a reliable connection use the plug with a fitting that has an internal 37Â° cone (female receptacle) sized for the matching UNF thread and cone geometry, or select a fitting specifically specified to pair with the JIC plug with UNF GZ in carbon steel, type ROV Format.
