Product view and oval section schematicType R Oval Ring Joint Gasket
Oval metal ring, chosen for the flange groove type and ring number
The Type R oval ring joint gasket is a solid metal sealing ring for Type R ring joint flanges. As the joint is tightened, the oval cross-section establishes sealing contact with the mating groove. It is primarily used in piping, valves, and pressure equipment designed for the corresponding Type R oval ring.

Features
- Solid metal construction for high-pressure ring joint flanges.
- Oval sections pair with the corresponding flat-bottom or round-bottom Type R grooves, with groove geometry and ring number selected for the flange design.
- Selected by Type R ring number and material. Nonstandard requirements are addressed through equipment drawings and technical specifications.
- Materials can be selected to suit the medium, flange material, and design conditions.
Materials & configurations
| Component / Item | Material Options and Specification Details |
|---|---|
| Material options | Soft iron, low-carbon steel, and stainless steels such as 304 and 316; material condition and hardness selected for the corresponding standard and mating flange |
| Surface condition | Uncoated or with an appropriate specified surface treatment |
| Product identification | Type R, oval cross-section, ring number, material, and applicable standard |
Standards & supply options
- ASME B16.20 or API Specification 6A, selected for the flange and equipment. Ring number, material, hardness and surface condition follow the corresponding standard.
Typical applications
- Oil and gas piping flanges designed for Type R oval rings.
- High-pressure valves, pressure vessels, and associated process equipment.
- Existing installations where the original flange design specifies an oval ring.
Selection & service notes
The oval section pairs with its matching Type R groove. Selection includes groove geometry, ring number, material, hardness and applicable standard. Groove geometry determines compatibility with oval or octagonal sections; RX and BX are separate ring joint types.
