PG Metallic RTJ (Ring
Type Joint) Gaskets

Solid metal gaskets precision-machined for high-pressure, high-temperature flange connections in critical oil, gas, and petrochemical service.

what it does

Metal-to-Metal Sealing for Extreme Pressure

Metallic RTJ gaskets create a leak-tight seal through controlled metal deformation inside precision-machined flange grooves, ensuring integrity under severe pressure and temperature conditions.

CoRE FEATURES

Designed for High-Pressure Applications

Solid Metal Construction

Machined from forged metal rings designed for compressive sealing in ring joint flanges.

Metal-to-Metal Deformation Seal

Bolt load compresses ring, forming tight flange seal.

Surface Finish Control

Matches ASME and API groove tolerances.

Compliant with Industry Standards

Manufactured to ASME B16.20, API 6A, and API 17D specifications.

Product information

Configured for Extreme Service Conditions

Engineered for high bolt loads, precision groove engagement, and critical pressure containment across demanding oil, gas, and industrial environments.

Types

R Type (Oval & Octagonal)

Standard pressure RTJ profile for API 6A and ASME B16.20 flanges, available in oval and octagonal configurations.

RX Type

Pressure-energized design improving sealing efficiency for higher-pressure API flange systems.

BX Type

High-pressure gasket for API 6A flanges, designed for very high bolt loads and internal pressures.

IX Seal Rings

Compact, high-integrity sealing rings engineered for subsea and specialized high-performance applications.
