2" & 3" Fig 1502 Hammer Union Seals in NBR, HNBR, and FKM

2" & 3" Fig 1502 Hammer Union Seals in NBR, HNBR, and FKM

1. Product Introduction

---

Our Fig 1502 Hammer Union Seals are engineered for the most demanding environments in the oil and gas industry. Specifically designed for 2-inch and 3-inch high-pressure piping systems, match the replacement lip profile and backup arrangement to the manufacturer drawing. Confirm the complete assembly rating for any proposed 15,000 PSI CWP service.

Whether you are involved in hydraulic fracturing (fracking), cementing, acidizing, or nitrogen service, confirm the specific compound, groove dimensions and operating requirements before replacement.

2. Material Comparison & Technical Selection

---

We offer three primary elastomeric compounds to match your specific wellbore conditions. Choosing the right material is key to preventing premature seal failure.

3. Technical Specifications

---

• Size Availability: 1", 2", 3", 4" (Specializing in 2" & 3" for Fig 1502).

• Working Pressure: Refer to the complete identified union assembly rating; the rubber alone has no independent pressure rating.

• Design Type: Pressure-energized Lip Type Seal.

• Reinforcement: Optional Brass or Stainless Steel backup construction matched to the manufacturer drawing.

• Compatibility: Confirm manufacturer, nominal size, groove and seal drawing; Figure 1502 alone does not establish interchangeability.

4. Key Features & Benefits

---

• Anti-Extrusion Design: Confirm lip profile, clearances and backup construction for the actual pressure cycling duty.

• Chemical Compatibility: Review the actual fluid formulation, concentration, temperature and exposure against the selected compound.

• Precision Manufacturing: Agree dimensions and tolerances from the specific manufacturer seal and groove drawing.

• Sour-Service Selection: Confirm specific compound qualification for Sour Service, including gas composition, temperature, pressure and decompression duty.

5. Common Applications

---

Our hammer union seals are essential components in:

• Frac Manifolds & Discharge Lines

• Cementing & Acidizing Units

• Wellhead Flowlines

• Identified hammer union connections on compatible control-line equipment; confirm the equipment drawing and service limits

• High-Pressure Water-blast Equipment

•  
•  
•  

6. Quality Assurance & Testing

---

We understand that seal failure leads to costly non-productive time (NPT). Agree the required inspection and test documentation for the selected configuration:

• Hardness Testing (Shore A): Agree one compound hardness and tolerance; hardness alone does not establish pressure capability.

• Tensile & Elongation Tests: Verifying material toughness.

• Compression Set Testing: Ensuring the seal regains its shape for reliable long-term performance.

• Batch Traceability: Agree compound identification, production-date records and required inspection documentation when ordering.

7. Frequently Asked Questions (FAQ)

Q: Why use a brass ring in a Fig 1502 seal?
A: A correctly specified backup supports the elastomer against extrusion into clearances. Confirm its material, dimensions and retention from the manufacturer drawing; it does not create an independent pressure rating for the rubber.

Q: Can I use NBR seals for Sour Gas (H2S) service?
A: Review the exact compound against the actual gas composition, exposure, temperature, pressure and decompression duty. A family name such as NBR, HNBR or FKM alone does not establish sour-service qualification.

Ordering 2-inch and 3-inch Fig 1502 Seals Separately

Use separate order lines for nominal 2-inch and 3-inch unions. Confirm the manufacturer marking, groove drawing and seal profile for each size rather than scaling dimensions from the other. Provide photographs of both seal faces, side profile and backup arrangement, together with compound, hardness tolerance and service conditions. Approve each size-specific configuration before repeat supply.
