Weco Hammer Union Seals (Lip Seals)

Hammer union seals (also known as Weco Seals) are used for hammer joint type pipe connections to establish flow lines and prevent leakage. Hammer joints are manufactured by companies such as Weco, FMC and Kemper valve and are used in the oil and gas industry. Widely used in cementing, fracturing, acidizing, testing, and choke-and-kill lines.

HST developed different materials to suit for hostile working conditions such as H2S and CO2. Ideal for creating secure, leak-proof connections in high-pressure oilfield operations.

All offered Hammer Union Lip Seals/Weco Seals are 100% "Made in Europe" and can be supplied with 3.1 Certificate and CoO!
