Product description

Product details

Our premium Hammer Union Seals are engineered to provide reliable, leak-proof connections in the most challenging oil and gas environments. These essential sealing components are widely utilized in high-pressure flowlines, including hydraulic fracturing (fracking), well cementing, acidizing, and flowback operations. Designed to withstand the extreme rigors of both onshore and offshore drilling, our seals perform optimally in manifolds, pump systems, and high-vibration piping assemblies. Whether used in standard service or high-pressure Figure 1502, 1002, or 602 unions, these seals ensure operational integrity and safety during critical fluid transfer processes.

The core functionality of our Hammer Union Lip Seals lies in their precision-molded geometry, which allows the seal to expand under pressure for a tighter fit against the union wall. This self-energizing design is crucial for preventing leaks in systems subject to high flow velocities and mechanical stress. To enhance durability in ultra-high-pressure scenarios, reaching up to 15,000 PSI, our seals often feature integrated Brass or Stainless Steel backup rings. This reinforcement prevents rubber extrusion and deformation, significantly extending the service life of the gasket and reducing costly maintenance downtime in the field.

Selecting the right material is vital for chemical compatibility and longevity in the oilfield. We offer Hammer Union Seals in a range of high-grade elastomers to meet specific site requirements. Nitrile (NBR) is the preferred choice for general oil and water service, offering excellent abrasion resistance. For high-temperature environments or exposure to aggressive chemicals, our Viton (FKM) seals provide superior thermal stability. For the most demanding "Sour Gas" (H2S) applications, we provide HNBR (Hydrogenated Nitrile) seals, which are specifically formulated to resist chemical degradation and explosive decompression.

Frequently asked questions

A Hammer Union Seal is a high-pressure gasket used in the oil and gas industry to create a leak-proof connection between male and female sub-ends of a hammer union. Its primary function is to prevent fluid or gas leakage in high-pressure flowlines, manifolds, and fracking equipment, ensuring safe and efficient drilling operations.

Hammer Union Seals are typically manufactured from high-performance elastomers to withstand harsh oilfield conditions. Common materials include: 1. Nitrile (NBR): For general oil and water service. 2. FKM: For high-temperature and chemical resistance. 3. HNBR: Ideal for sour gas (H2S) service and higher temperature applications.

Choosing the right seal depends on three main factors: 1. Figure Number: Match the seal to your union type (e.g., Fig 602, Fig 1002, Fig 1502). 2. Pipe Size: Common sizes range from 1" to 12". 3. Service Condition: Consider the pressure, temperature, and whether the media is corrosive or contains H2S (Sour Gas).

In high-pressure environments (above 6,000 PSI), rubber alone may "extrude" or deform into the gaps of the metal union. A Brass or Stainless Steel backup ring provides structural reinforcement, maintaining the seal's shape and preventing failure under extreme mechanical stress.

Yes, but you must select the correct material. For Sour Gas (H2S) service, it is recommended to use HNBR or FKM Hammer Union Seals. These materials are specifically engineered to resist chemical degradation and hydrogen embrittlement caused by sour crude and gas.

The temperature range depends on the elastomer: 1. NBR: -30°C to +100°C (-22°F to +212°F) 2. FKM: -20°C to +200°C (-4°F to +392°F) 3. HNBR: -40°C to +150°C (-40°F to +302°F)
