R Series A 1

Description

R Series A 1:

The R Series A1 Ring Type Joint (RTJ) Gasket is engineered for high-integrity sealing in high-pressure environments, complying with ASME B16.20, ASME B16.47 Series A1, and API 6A standards. These gaskets are available in sizes ranging from ½” to 36” and pressure classes from 150 to 2500 (ASME) and 300 to 900 (Series A1), making them a versatile choice across industrial applications.

Manufactured with an octagonal cross-section, the R Series A1 provides superior sealing performance compared to oval rings and is interchangeable on modern octagonal grooved flanges. Suitable for use with flat or round bottom groove flanges, it ensures metal-to-metal contact sealing, even under extreme pressures.

The R Series A1 is the preferred choice for engineers seeking durability, compatibility, and optimal sealing performance in critical pipeline and process equipment.
