Is the ORFS Straight Bulkhead Nipple with UNF Male Thread, Carbon Steel, Type SV compatible with standard ORFS ports and does it require a specific O-ring size for proper sealing?

ORFS Straight Bulkhead Nipple with UNF Male Thread, Carbon Steel, Type SV is designed to be compatible with standard ORFS ports. The fitting uses a flat-face ORFS sealing surface with an O-ring seated in the groove on the face, which mates with the corresponding flat port to provide a reliable, high-pressure seal. For proper sealing the correct O-ring size and material are required—typically the O-ring must match the groove dimensions of the Type SV face and be appropriate for the hydraulic fluid and pressure/temperature conditions. While standard ORFS fittings commonly use metric or inch O-rings per industry norms, confirm the exact O-ring inner diameter, cross-section (thickness) and material from the product’s technical drawing or supplier specification to ensure a proper fit and compatibility.

Can the ORFS Straight Bulkhead Nipple with UNF Male Thread, Carbon Steel, Type SV be used in high-vibration applications without additional locking or retightening procedures?

ORFS Straight Bulkhead Nipple with UNF Male Thread, Carbon Steel, Type SV can perform well in many vibration-prone environments thanks to its O‑ring flat‑face seal and robust carbon‑steel construction with galvanized finish, which together resist leakage, corrosion and mechanical wear. However, high‑vibration applications can promote thread loosening and O‑ring extrusion over time. The product description does not explicitly state integrated anti‑vibration locking features (e.g., positive locking washer, safety wire, or prevailing‑torque thread), nor does it provide guaranteed torque/retorque intervals for such conditions. Recommendation: for continuous or severe vibration use, apply industry best practices — proper torque to the manufacturer’s spec, use of an appropriate thread locking method or mechanical retention (lock washer, safety clip, or adhesive rated for hydraulic service), and scheduled inspections/retightening. If permanent vibration resistance without additional measures is required, consult the manufacturer’s technical data sheet or their engineering support to confirm suitability or request vibration‑tested alternatives.
