Ring Joint Gaskets - Pumps, Valves, Piping and Fittings
Metallic ring joint gaskets provide high-integrity, metal-to-metal sealing for flanged connections in marine pumps, valves, piping and fittings. They are used where high pressure, temperature, vibration resistance and reliable leak prevention are required.
ProShipWorks provides end-to-end support to source and supply Ring Joint Gaskets for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | ASME B16.20 covers metallic gaskets for pipe flanges, including ring joint gaskets. API 6A specifies ring joint gasket requirements for wellhead and tree equipment. Material certification and dimensional inspection should follow the purchase specification. |
|---|---|
| Class Approval | Classification societies such as DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK may accept ring joint gaskets as part of approved piping or machinery assemblies. Approval depends on the complete system, material certificates and applicable vessel rules. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify ring number, type, material, hardness and flange compatibility before installation. Clean the grooves and flange faces, inspect for damage, align the joint correctly and install a new gasket. Do not reuse ring joint gaskets or force them into damaged grooves. |
|---|---|
| Maintenance Tips | Inspect for leakage, corrosion, deformation and flange damage during maintenance. Replace the gasket after disassembly and check flange alignment, groove condition and bolting torque according to the equipment maker's procedure. |
| Safety Notes | Depressurize, drain and isolate the system before opening the joint. Confirm the gasket material is compatible with pressure, temperature and fluid conditions. Use calibrated tools and approved tightening procedures, and never substitute a ring size or material without engineering approval. |
