Hammer Union Seals ensure reliable, high-pressure sealing and durability in demanding applications. They feature a robust elastomer design with optional metal reinforcement for added strength.

Suitable for cementing, fracturing, acidizing, testing, and choke-and-kill lines hammer union seals feature a specialized rubber seal ring that provides effective sealing with minimal torque. The snap-fit design secures the seal within the hub, preventing displacement.

HST offers FKM (Viton) hammer union seals, which provide superior resistance to high temperatures and harsh chemicals, making them ideal for demanding industrial applications (H2S resistance).
