A flange joint that leaks under high pressure can shut down a line, trigger costly repairs, and put people at risk.
Many conventional gaskets may fail under high pressure and temperature. An R Oval Ring Gasket provides a reliable metal-to-metal seal in RTJ flange grooves, ensuring better sealing performance and joint integrity in demanding conditions. It is ideal for critical industrial applications requiring durability and dependable leak prevention.
Clarion Industrial is a trusted R Oval Ring Gasket Supplier, providing rings made to your drawings and specifications. Get the right size, material, and finish for reliable sealing and lasting performance.
Overview of R Oval Ring Gasket
R Oval Ring Gasket is a precision-machined metal seal designed for Ring Type Joint (RTJ) flanges, providing reliable sealing and durability in high-pressure, high-temperature applications. When you tighten the bolts, the ring deforms slightly against the groove walls. It creates a reliable metal-to-metal seal under high pressure and temperature.
These rings are widely used in oil and gas, refining, petrochemical, and process industries. Manufactured to ASME B16.20 dimensions, with API 6A compliance available where applicable, oval rings cover sizes R11 to R105 and suit both round-bottom and flat-bottom grooves.
Long-term performance of R Oval Ring Gasket depends on the entire joint, including groove dimensions, material compatibility, bolting, and careful installation.
Key Features
Reliable metal-to-metal sealing:
The ring deforms against the groove walls under bolt load, forming a tight, leak-resistant seal.
Precision-machined oval cross-section:
Accurate machining gives consistent contact with the flange groove, so the ring seats evenly.
Built for high-pressure RTJ flange systems:
Designed for Ring Type Joint connections, it provides reliable sealing where soft gaskets cannot withstand high pressure.
Suitable for elevated temperatures:
Heat performance depends on the material, so we match grades to your service temperature.
Wide range of metallic grades:
Choose soft iron, stainless steel, duplex, Inconel, Monel, or titanium to suit your media.
Custom sizes, materials, and finishes:
We review non-standard requirements against your drawings, flange standards, and project specifications before production.

Why Choose Clarion
Clarion Industrial is a Houston-based manufacturer and supplier of industrial fasteners and precision-engineered components with over 25 years of experience. As an R Oval Ring Gasket Supplier in Houston, Clarion provides gaskets made to your drawings and specifications, with inspection, testing, and documentation available as needed.
Some flanges need a different ring style. BX-Type Ring Gaskets, including the API 6BX Ring Gasket, are designed for API 6BX flanges and are not interchangeable with oval rings. Share your flange type and applicable standard to help us recommend the correct ring style.

Get Your R Oval Ring Gasket QuoteFrequently Asked Questions
1. Can an R Oval Ring Gasket be reused after the flange is opened?
Reuse is not recommended. The ring deforms during initial seating, so always use a new gasket when reassembling the joint.
2. Can an R Oval Ring Gasket be used on raised-face flanges?
No. It only works with RTJ flanges that have a machined ring groove matching the gasket’s ring number.
3. Why should an R oval ring gasket be softer than the flange?
The ring needs to deform to seal. A softer gasket yields first, which protects the groove faces from damage.
4. How should you handle an R Oval Ring Gasket before installation?
Keep it clean and free from scratches or damage. Inspect the ring before installation to prevent leaks.
5. Can an R Oval Ring Gasket replace a BX-Type Ring Gasket?
No. BX-Type Ring Gaskets are designed for API 6BX flanges and cannot be used interchangeably with R Oval Ring Gaskets due to their different designs.
6. How should flange bolts be tightened with an R Oval Ring Gasket?
Tighten gradually in a cross-pattern sequence, so the ring seats evenly in the groove and the load spreads uniformly.
