The 3" Figure 1502 Male Blind Sub with Wing Nut is a robust, high-pressure closure assembly engineered to securely cap off and isolate the female threaded hub of a hammer union connection. Designed for the extreme conditions of the oilfield, this integrated blind fitting is rated for a Cold Working Pressure (CWP) of 15,000 PSI. It is an essential component for dead-ending flowlines, capping well-testing manifolds, and securing hydraulic fracturing equipment where absolute fluid containment is mandatory.

Manufactured from premium high-strength forged alloy steel, this complete assembly includes the precision-machined male blind sub (featuring the elastomeric seal groove) and the heavy-duty Figure 1502 wing nut. Because it comes pre-assembled with the wing nut, rig crews can immediately deploy the blind to mate with any standard 3" 1502 female sub, utilizing a sledgehammer for rapid, secure make-up.

Built to withstand abrasive frac fluids, severe mechanical shock, and intense vibration, the 3" 1502 Male Blind Sub with Wing Nut ensures maximum safety, blowout-proof performance, and structural integrity in the most demanding upstream applications.

Features & Benefits

  • Complete Assembly: Comes fully equipped with the male blind sub and heavy-duty wing nut for immediate field deployment.

  • 15,000 PSI CWP Rating: Specifically engineered to safely contain extreme pressures in critical well-control and stimulation environments.

  • Forged Alloy Steel Construction: Delivers superior structural strength, resisting fatigue, mechanical impact, and internal erosion.

  • Positive Isolation: Provides a secure, blowout-proof dead-end for high-pressure fluid and gas lines.

  • Standard Interchangeability: Fully compatible with all industry-standard 3" Figure 1502 female threaded hubs.

  • Rapid Field Deployment: Allows for fast make-up and break-out, minimizing downtime during fast-paced rig-up and manifold adjustments.
