A complete ring type joint gasket portfolio covering soft iron, low carbon steel, SS316, SS304, Monel, and Inconel materials — engineered for high-pressure and high-temperature RTJ flanged joints across global markets.
The most economical ring type joint gasket, used for low-pressure and moderate-temperature RTJ flanged joints. Soft iron RTJ gaskets conform easily to the groove and provide reliable sealing.
Compliance: ASME B16.20
Applications: General industry, low-pressure RTJ joints
Hardness: Approx. 90 HB
Used for higher-pressure RTJ joints where soft iron is not sufficient. Low carbon steel RTJ gaskets provide higher strength and better resistance to deformation under pressure.
Compliance: ASME B16.20
Applications: Oil & Gas, high-pressure RTJ joints
Hardness: Approx. 120 HB
The most widely specified ring type joint gasket for corrosive and high-temperature service. SS316 RTJ gaskets provide excellent corrosion resistance and reliable sealing performance.
Compliance: ASME B16.20, API 6A
Applications: Petrochemical, refinery, chemical processing
Hardness: Approx. 160 HB
Cost-effective ring type joint gaskets for standard industrial applications. SS304 RTJ gaskets provide good corrosion resistance and reliable sealing for moderate service conditions.
Compliance: ASME B16.20
Applications: General industry, utilities, process piping
Hardness: Approx. 160 HB
Specified for highly corrosive media and seawater service. Monel RTJ gaskets provide excellent resistance to acids, alkalis, and chloride environments.
Compliance: ASME B16.20
Applications: Marine, chemical, high-corrosion service
Hardness: Approx. 110 HB
Designed for the most demanding high-temperature and high-pressure applications. Inconel RTJ gaskets provide superior oxidation resistance and mechanical strength at elevated temperatures.
Compliance: ASME B16.20, API 6A
Applications: Subsea, nuclear, high-temperature service
Hardness: Approx. 180 HB
A ring type joint (RTJ) gasket is a metal sealing ring that fits into a machined groove on the flange face. When the flanges are bolted together, the gasket is compressed into the groove, creating a metal-to-metal seal that is highly resistant to pressure and temperature. RTJ gaskets are commonly specified for high-pressure and high-temperature applications where standard gaskets cannot perform.
This construction allows ring type joint gaskets to perform reliably in the most demanding industrial environments — from high-pressure Oil & Gas wellheads to subsea and high-temperature refinery operations. Every RTJ gasket we supply is manufactured to ASME B16.20 dimensional standards.

Correct RTJ gasket selection is critical to ensuring a leak-free flanged joint and long-term operational safety. The material and groove style must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing a ring type joint gasket:
If you are unsure which ring type joint gasket specification best suits your application, our technical team is available to review your flange drawings, process data, and project specifications — and recommend the most suitable RTJ sealing solution.
We specialize in ring type joint gasket supply — offering soft iron, low carbon steel, SS316, SS304, Monel, Inconel, and Hastelloy materials in all major groove styles (R, RX, BX). Every gasket is manufactured to ASME B16.20 standards.
We supply RTJ gaskets in Style R (octagonal), Style R (oval), Style RX, and Style BX — from ½" to 24" as standard, with larger sizes and custom configurations on request.
