HNBR Hammer Union Seals With Stainless Ring: Superior Heat & Abrasion Resistance

Overview

Our high-performance HNBR Hammer Union Seals with Stainless Steel Rings are specifically engineered for the rigorous demands of the oil and gas industry. By combining the advanced chemical resistance of Hydrogenated Nitrile (HNBR) with the structural integrity of a stainless steel anti-extrusion ring, these seals provide a reliable, leak-proof solution for high-pressure flow control equipment.

Key Features and Benefits

---

• Enhanced Thermal Stability: HNBR provides superior heat resistance compared to standard Nitrile (NBR), maintaining seal integrity in high-temperature environments.

• Anti-Extrusion Technology: The integrated Stainless Steel Ring prevents the elastomer from extruding under extreme pressure, significantly extending the service life of the seal.

• Extreme Abrasion Resistance: Designed to withstand the erosive effects of abrasive media, including drilling mud, fracturing fluids, and proppants.

• Chemical & H2S Compatibility: Excellent resistance to crude oil, sour gas (H2S), CO2, and common oilfield chemicals.

• Precision Fit: Manufactured to meet strict industry tolerances, ensuring a perfect match with standard hammer union configurations.
