What is a Soft Iron RTJ Gasket and Why is it Used?
A Soft Iron RTJ Gasket is a precision machined metallic sealing ring that is used in high-pressure and high-temperature flange connections. The gasket seals by wedging action, between the gasket and its flange grooves. As the bolt load is applied, the gasket material will deform and flow into the micro-fine irregularities present in the harder flange material, resulting in a strong, metal-to-metal seal.
Soft iron is the ideal material for these gaskets. With a low hardness (approximately 90 HB), it is softer than the steel flanges it mates with. This ensures the gasket deforms without damaging the more expensive flange, making it an ideal sacrificial sealing component. Soft iron is an inexpensive option and provides excellent sealing capabilities in numerous industrial environments.
Our Extensive Range of Soft Iron RTJ Gaskets
We manufacture and stock a wide variety of Soft Iron Ring Type Joint Gaskets to suit all your project requirements, all available for quick delivery.
- Soft Iron Oval Ring Joint Gaskets: Our Oval gaskets are the original design for RTJ flanges. These gaskets are highly effective in sealing flat-bottomed grooves and are frequently used in older flanged connections. Their rounded profile ensures a solid initial contact seal.
- Soft Iron Octagonal Ring Joint Gaskets: The Octagonal design is a modern and more efficient alternative. It provides a superior sealing efficiency compared to the oval type, as its straight-sided profile offers a larger contact area with the flange grooves. This design is widely used in new and high-pressure flange installations.
- Soft Iron RX-Type RTJ Gaskets: These gaskets are specifically designed for higher pressures and can be used in the same flange grooves as standard R-type gaskets. The RX design utilizes a pressure-energized seal, where the internal fluid pressure enhances the sealing performance. This makes it ideal for use in API 6A flanges.
- Soft Iron BX-Type RTJ Gaskets: The Soft Iron BX-RTJ Gaskets are designed for use with API 6A flanges at extremely high pressures (up to 20,000 psi). This gasket relies on the effect of pressure, making it the most reliable choice for critical applications where a full-face seal is required.

Soft Iron vs. Low Carbon Steel RTJ Gaskets — Which Should You Choose?
Choosing the right RTJ gasket material depends on your flange specification, operating pressure, and fluid type. Soft iron and low carbon steel are the two most common material grades for Ring Type Joint gaskets under ASME B16.20. Here is a direct comparison to help you select the right option:
| Property | Soft Iron | Low Carbon Steel |
|---|---|---|
| Hardness (Max HB) | 90 HB | 120 – 140 HB |
| Standard | ASME B16.20 | ASME B16.20 |
| Ideal Application | Standard oil & gas flanges, ASME B16.5 / B16.47 | High-abrasion, high-cycle environments |
| Flange Compatibility | Carbon steel, SS, alloy steel flanges (harder) | Alloy and stainless steel flanges |
| Sealing Performance | Excellent — deforms to fill micro-irregularities | Good — slightly less conformable |
| Risk of Flange Damage | Very low — gasket yields first | Low — harder than soft iron |
| Cost | Lower | Moderate |
| Reusability | Single-use only | Single-use only |
| Availability at Jade Alloys | ✓ In stock — all R, RX, BX types | ✓ Available on request |

Request a QuoteFrequently Asked Questions
What is the hardness of a Soft Iron RTJ Gasket?
Soft iron is typically rated at approximately 90 HB (Brinell Hardness), making it softer than the flanges it is intended to seal.
What is the primary difference between Oval and Octagonal RTJ Gaskets?
Oval gaskets are an older design for flat-bottomed grooves. Octagonal gaskets, a newer design, provide a more efficient line contact seal and are preferred for most modern flange applications.
Are Soft Iron RTJ Gaskets reusable?
No, Soft Iron RTJ Gaskets are designed to deform and create a seal when compressed. Once a gasket has been used, it should always be replaced to ensure a safe, leak-proof connection.
What is the difference between Soft Iron and Low Carbon Steel RTJ Gaskets?
Soft iron RTJ gaskets have a maximum hardness of 90 HB, making them softer and more conformable than low carbon steel gaskets (typically 120–140 HB). Soft iron is preferred for standard oil and gas flanges where the gasket must deform without damaging the flange face. Low carbon steel is used in higher-abrasion environments. Both are single-use and conform to ASME B16.20.
Can Soft Iron RTJ Gaskets be used with stainless steel flanges?
Yes. Soft iron RTJ gaskets (max 90 HB) are softer than stainless steel flanges (160–200 HB), so they deform correctly on bolt load without damaging the flange groove. They are widely used with ASTM A182 F316, F304, and F321 stainless steel flanges in chemical and oil & gas applications.
What is the maximum pressure rating for a Soft Iron BX-Type RTJ Gasket?
Soft Iron BX-Type RTJ Gaskets are designed for API 6A flanges and can handle pressures up to 20,000 psi. The BX design uses a pressure-energised seal where internal fluid pressure increases the sealing force, making it the most reliable choice for subsea and wellhead applications.
How do I select between R, RX, and BX type Soft Iron RTJ Gaskets?
Use Type R (Oval or Octagonal) for standard ASME B16.5 / B16.47 flanges across all pressure classes. Use Type RX when higher pressure is needed — RX fits the same groove as R-type but adds pressure-energised sealing. Use Type BX exclusively with API 6A flanges at 5,000–20,000 psi. If unsure, share your flange drawing and pressure class with our team for a recommendation.
Do you supply Soft Iron RTJ Gaskets to UAE, Dubai, and the Middle East?
Yes. Jade Special Metals is an active exporter of Soft Iron RTJ Gaskets to the UAE (Dubai and Abu Dhabi), Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain. We have established logistics partners for fast delivery across the GCC region. Contact us at sales@jadealloys.com for pricing and lead times for your country.
What is the lead time for custom-size Soft Iron RTJ Gaskets?
Standard sizes (R-1 to R-99 and BX-150 to BX-410) are available from stock for immediate dispatch. Custom sizes — including non-standard bore diameters, special OD/ID combinations, and non-standard pressure classes — typically require 7–14 business days from drawing approval. Contact our team with your specification for a confirmed lead time.
