2" 15,000 PSI Fig 1502 Hammer Union Retainer Ring – Oil & Gas Fitting

The 2" Figure 1502 Retainer Ring is a critical replacement component engineered to safely and securely lock the wing nut onto the male sub of a high-pressure hammer union assembly. Designed for use in 15,000 PSI Cold Working Pressure (CWP) systems, this retaining ring (often referred to as a segment ring or snap ring) ensures that the union remains fully assembled and structurally sound during transport, rig-up, and extreme-duty pumping operations.

Manufactured from high-strength, heat-treated steel, this retainer ring is built to withstand the heavy mechanical shock, vibration, and rigorous handling typical of upstream environments. It provides a precise, direct-fit replacement for worn or damaged rings, allowing operators to safely refurbish existing flowline iron rather than replacing the entire union assembly.

Designed for field reliability, the 2" 1502 Retainer Ring is an essential maintenance item for keeping your hydraulic fracturing, cementing, and well-testing flowlines operating safely and efficiently.

Features & Benefits

• Secure Nut Retention: Firmly locks the heavy-duty wing nut onto the male sub, preventing accidental disassembly in the field.

• 15,000 PSI Compatibility: Designed to maintain the structural integrity of Figure 1502 hammer unions operating at 15M pressures.

• High-Strength Steel: Manufactured from premium, heat-treated materials to resist deformation, wear, and mechanical failure.

• Direct Replacement: Precision-engineered to perfectly fit standard 2" Figure 1502 male subs and wing nuts.

• Cost-Effective Maintenance: Allows for the safe repair and refurbishment of existing flowline iron, extending the lifespan of your equipment.

• Field Essential: A crucial spare part for rapid on-site repairs during frac rig-ups and flowline maintenance.

Specifications & Technical Details

Applications
