2" Weco Hammer Union Seal (Brass Insert & Buna-N) - Import | Cost-Effective Anti-Extrusion Seal

The 2" Weco Hammer Union Seal (Import) featuring a precision-machined Brass insert and Buna-N (Nitrile) elastomer is a highly economical, reliable sealing solution engineered for high-pressure flowline applications. Designed to fit seamlessly into standard 2-inch Weco-style hammer unions, such as Figure 1502 profiles, this composite seal ring provides vital protection against fluid bypass and seal blowout while offering a budget-friendly option for high-volume maintenance and operations.

Sourced from trusted international manufacturing partners, our "Import" line is carefully selected to deliver exceptional value without compromising essential field safety. The core of this seal is molded from high-grade Buna-N (Nitrile / NBR), providing excellent resistance to petroleum-based fluids, water, and drilling muds. It features the crucial integration of a rigid Brass Anti-Extrusion Ring. During extreme pressure spikes, this metallic backup ring structurally reinforces the elastomer lip, preventing it from extruding into the clearance gap of the union. This guarantees a tight, dynamic, and blowout-proof seal under demanding conditions.

Ideal for operators seeking to balance operational budgets with high-pressure reliability, this 2" Brass/Buna Import Weco seal is the perfect choice for standard service flowline connections that require frequent maintenance and part replacement.

Features & Benefits

• Cost-Effective Value: An economical "Import" alternative that reduces maintenance overhead for high-volume flowline operations without sacrificing seal integrity.

• Brass Anti-Extrusion Ring: Integrated non-sparking metal backing entirely prevents elastomer extrusion and blowout under severe pressure surges.

• Buna-N Elastomer: Formulated from Nitrile rubber for dependable resistance to oil, gas, water, and abrasive fracturing or drilling fluids.

• Pressure-Energized Geometry: Utilizes internal line pressure to actively expand the sealing lips against the union's surfaces, creating a barrier that strengthens as pressure increases.

• Exact Fitment: Precision manufactured to ensure a perfect, drop-in fit for standard 2" Weco-style hammer unions, allowing for rapid in-field turnarounds.

Specifications & Technical Details

Applications

This 2" Brass/Buna Import Weco Seal is recommended for standard service flowline environments where cost-efficiency and volume replacement are key. Typical applications include cementing and circulating lines, high-pressure pump discharge lines, fluid transfer manifolds, and general well-servicing equipment where extrusion resistance is required.

Quality Assurance

While part of our highly competitive import line, these seals are still subjected to strict batch-testing protocols. We verify the Buna-N durometer (hardness) and dimensionally inspect the brass anti-extrusion rings to ensure they meet the rigorous tolerance standards necessary to protect your field personnel and flowline equipment.
