Hammer Unions are made by Weco, FMC, and Kemper Valve among others, and are used in the Oil & Gas Industry, in steel mills, chemical plants, strip mining, and marine dredging.

Hammer Union Seals are utilized in hammer union-style pipe connections to create flow lines and prevent leakage. Hammer unions are especially designed to enjoin mud tanks immediately without managing the flanged connections.

The high-pressure union is a kind of connection head for connecting pipes. It will be affected by external factors such as working pressure, vibration, erosion, corrosion, etc. in the work, and it is easy to leak fluid media, resulting in the problem of safety accidents in which the seal is invalid. At present, the oil resources tend to be deeper strata and worse environment. Therefore, it is necessary to connect the union of the manifold to meet the complex working conditions and prevent the sealing failure of the union.

Recommended services for WECO hammer union seals: Cementing, fracturing, acidizing, testing, and choke-and-kill lines

Positive sealing: Primary elastomer seal and metal-to-metal seal combine to deliver positive sealing throughout the stated pressure range.

Hammer unions use a special rubber seal ring for positive sealing with minimum torque. This ring snap-fits into a detent within the hub to prevent its loss. Hammer unions are available in 1 in. to 4 in. line pipe sizes.

Seal Size: 1”, 1-1/4”, 1-1/2”, 2”, 2-1/2”, 3”, 4”

Seal Material: NBR, HNBR, FKM, Brass, Stainless Steel, etc.
