3" 15,000 PSI Fig 1502 Adjustable Choke Bonnet Repair Kit (Without Seal Piston)

The 3" Figure 1502 Adjustable Choke Bonnet Repair Kit is a specialized maintenance set designed for the routine servicing and pressure-sealing of high-pressure choke valves. Rated for 15,000 PSI Cold Working Pressure (CWP), this kit contains the critical soft goods and structural seals required to restore the integrity of the bonnet assembly. This specific configuration is provided without the seal piston, making it a cost-effective solution for operators whose pistons remain in serviceable condition or are managed as separate inventory items.

Each component in the kit is manufactured from high-performance elastomers and alloys—such as Viton, PTFE (Teflon), and stainless steel—to ensure maximum resistance to the abrasive drilling muds, sour gases (H2S), and corrosive chemicals encountered in upstream flowback and well-testing operations. By replacing worn stem packing, O-rings, and back-up rings, this kit prevents hazardous leaks around the bonnet and stem, ensuring precise flow regulation and operator safety.

Designed as a direct-fit replacement for industry-standard 3" 1502 adjustable chokes, this repair kit is essential for extending the service life of manifold iron and minimizing non-productive time (NPT) in the field.

Features & Benefits

• 15,000 PSI Compatibility: Engineered to maintain a bubble-tight seal under the extreme pressures of 15M choke and kill systems.

• Targeted Maintenance: Specifically excludes the seal piston to reduce costs for standard "soft-good" seal replacements.

• Extreme Chemical Resistance: High-grade seals withstand exposure to hydrocarbons, CO2, H2S, and abrasive fracturing fluids.

• Reduced Friction: Premium stem packing materials ensure smooth manual or automated adjustment of the choke needle.

• Comprehensive Seal Set: Includes all necessary O-rings, back-up rings, junk rings, and packing required for a bonnet rebuild.

• Field-Ready Durability: Components are packaged for long-term storage and immediate deployment in harsh oilfield environments.

Specifications & Technical Details

Applications

This repair kit is required for the preventative maintenance and repair of 3" 15,000 PSI adjustable chokes. It is widely used on choke and kill manifolds, well-testing flowlines, frac flowback skids, and high-pressure production headers where the bonnet-to-body or stem-to-bonnet seals have been compromised by wear or thermal cycling.

Quality Assurance

Every component in the 3" 1502 Bonnet Repair Kit undergoes rigorous quality inspection. Elastomers are verified for durometer and material composition, and all metal backup rings are precision-machined to ensure perfect fitment and blowout-proof performance under maximum 15,000 PSI operational loads.
