Stainless Steel RTJ Gaskets

Stainless Steel RTJ Gaskets are the gold standard for high-integrity sealing in high-pressure and high-temperature flange connections. As a direct Manufacturer and Supplier of Stainless Steel Ring Type Joint Gaskets, Jade Special Metals controls every stage of production from raw material sourcing to final inspection ensuring each SS RTJ Gasket meets or exceeds API 6A and ASME B16.20 requirements. With ready stock across all common grades and sizes, and a proven global logistics network, we deliver on time to project sites in over 60 countries.

What is a Stainless Steel RTJ Gasket?

A Stainless Steel RTJ Gasket (Ring Type Joint Gasket) is a solid metallic sealing ring precision-machined to fit into a grooved flange face. When flange bolts are tightened, the gasket deforms plastically into the groove, creating an extremely tight, leak-proof seal that is far superior to soft or composite gaskets.

The inherent properties of stainless steel are high tensile strength, excellent corrosion resistance, and thermal stability make Stainless Steel Gaskets the preferred sealing solution for critical service conditions in oil & gas, petrochemical, and power generation industries. These gaskets are manufactured in strict conformance with RTJ Gasket standards API 6A and ASME B16.20. 

Types of Stainless Steel RTJ Gaskets

We supply all standard profiles of Stainless Steel Ring Type Joint Gaskets to match every flange design and pressure class:

  • Style R — Oval & Octagonal – UP TO 5,000 PSI
    The most widely used RTJ profiles. The octagonal cross-section offers superior sealing efficiency over the oval due to greater flange groove contact. Suitable for standard and medium-pressure applications.
  • Style RX – HIGH PRESSURE
    Designed to fit API 6A standard flanges. The RX profile leverages internal system pressure to enhance sealing force, the higher the pressure, the tighter the seal. Ideal for demanding oil & gas service.
  • Style BX – UP TO 20,000 PSI
    Engineered for extreme-pressure wellhead applications using API 6A BX flanges. These gaskets cannot be interchanged with R or RX types and are commonly found in subsea and wellhead equipment.

We also supply SBX and SRX profiles. Contact our team for availability.

Applications of Stainless Steel RTJ Gaskets

The high strength, corrosion resistance, and temperature tolerance of Stainless Steel Ring Type Joint Gaskets make them indispensable across critical industries:

  • Oil & Gas: Used in high-pressure pipelines, wellhead equipment, christmas trees, valves, and subsea connectors where zero leakage is mandatory.
  • Petrochemical & Refining: Ideal for sealing connections in refineries, chemical processing units, and reactor flanges handling aggressive media at elevated temperatures.
  • Power Generation: Used in steam lines, high-pressure boilers, superheaters, and turbine flanges where thermal cycling and extreme pressure demand reliable sealing.
  • Marine & Offshore: The corrosion resistance of stainless steel grades (particularly 316L) is perfectly suited for saltwater exposure, offshore platforms, and FPSO vessels.
  • LNG & Cryogenic: Low-carbon grades (304L, 316L) maintain toughness at cryogenic temperatures, making them suitable for LNG transfer lines and cryogenic storage connections.
  • Pharmaceutical & Food Processing: SS 316L and 304 grades meet hygienic requirements for pharmaceutical, biotech, and food-grade processing equipment flange sealing.

Frequently Asked Questions - Stainless steel RTJ Gaskets

What is the primary advantage of a Stainless Steel RTJ Gasket?

The main advantage is exceptional strength combined with corrosion resistance, high-pressure capability, and high-temperature tolerance. Stainless steel RTJ gaskets can handle pressures from 3,000 PSI up to 20,000 PSI (BX type) and temperatures from cryogenic to over 870°C, making them ideal where conventional soft gaskets would fail.

What grades of stainless steel are available for RTJ gaskets?

We supply RTJ gaskets in SS 304, 304L, 316, 316L, 321, 347, 410, and 440A. The most popular grades are SS 316 RTJ Gaskets (for superior corrosion resistance) and SS 304 RTJ Gaskets (for general industrial use). Custom grades are available upon request.

What is the difference between Style R, RX, and BX RTJ gaskets?

Style R (Oval/Octagonal) are the most common type, rated up to 5,000 PSI and used with standard ASME flanges. Style RX is designed for API 6A flanges and uses system pressure to enhance the seal — the higher the pressure, the tighter the seal. Style BX is for extreme-pressure wellhead applications, rated up to 20,000 PSI, and cannot be interchanged with R or RX types.

Are Stainless Steel RTJ gaskets reusable?

No. RTJ gaskets are single-use components. The gasket deforms plastically under bolt load to create the seal. Upon disassembly, the gasket must always be replaced with a new one to ensure an effective and safe seal during reassembly.

What standards do your Stainless Steel RTJ Gaskets conform to?

All our Stainless Steel Ring Type Joint Gaskets are manufactured and tested to API 6A and ASME B16.20 (formerly ANSI B16.20) standards. We provide EN 10204 3.1 material test certificates with heat and lot number traceability for every shipment.

Which industries commonly use Stainless Steel RTJ Gaskets?

Stainless Steel RTJ Gaskets are widely used in oil & gas (pipelines, wellheads, valves), petrochemical and refinery processes, power generation (steam lines, boilers), offshore and marine applications, LNG and cryogenic systems, and pharmaceutical or food-grade processing equipment.
