2"3"4" High Temperature Resistance Nitrile Hammer Union Lip Seal Gasket

2-, 3- and 4-Inch Nitrile Hammer Union Lip Seals — Temperature and Fit Selection

These nitrile (NBR/Buna-N) hammer union lip seals are selected for 2-, 3- or 4-inch nominal connections using the exact union figure and seal-pocket dimensions. The lip must match the mating seat and installation arrangement. Confirm the union manufacturer, profile drawing and construction before ordering a replacement.

A hammer union may use a lip seal or an O-ring according to its design and size. The nominal 2-, 3- and 4-inch sizes are connection designations, not seal inner diameters. Supply the union identification and measured seal dimensions so the replacement profile and backing arrangement can be checked.
For elevated-temperature oil service, specify the actual NBR compound and provide continuous temperature, short-duration peaks, exposure time, fluid additives and pressure cycles. A generic nitrile designation does not establish a maximum service temperature. FKM or HNBR alternatives require separate compatibility review; sour-gas applications need compound-specific qualification. Brass or stainless steel backing must match the approved union design.

Here are some of the benefits of using hammer union seals:

Quick and easy installation: Hammer union seals are easy to install and remove. This makes them a convenient option for applications where it is important to be able to quickly connect and disconnect pipes.
Matched sealing contact: Check lip condition, seal-pocket finish and correct seating before assembly. Sealing performance depends on the complete connection and service conditions.
Durable:Select compound requirements for heat exposure, compression set and fluid compatibility. Establish inspection and replacement intervals for the actual duty.
Cost-effective: Hammer union seals are a cost-effective option for sealing hammer union-style pipe connections.
