2" Nylon Choke Indicator – Replacement Part for Adjustable Chokes

The 2" Nylon Choke Indicator is a highly durable, precision-molded replacement component designed for large-bore, high-pressure adjustable choke assemblies. Used extensively in severe-service well testing, high-capacity flowback, and massive choke manifold operations, this indicator allows operators to visually and accurately determine the exact internal orifice size (stem travel) of the choke without requiring any equipment disassembly. Calibrated for large adjustable chokes with a maximum orifice capacity of 2 inches (128/64ths), it ensures highly precise flow control and pressure management during massive upstream fluid handling.

Manufactured from high-strength, industrial-grade nylon (engineered polymer), this indicator is specifically designed to completely eliminate the corrosion issues associated with standard metal dials. The heavy-duty nylon construction is 100% rust-proof and highly resistant to degradation from harsh frac chemicals, saline environments, and highly corrosive H2S sour gas conditions. Additionally, the nylon material is naturally non-sparking, providing an added layer of safety in volatile or explosive rig environments.

The indicator features deeply molded and color-contrasted markings, accurately calibrated in precise increments of 1/64th of an inch up to the full 2-inch maximum, providing a clear, highly legible readout for field personnel. Designed for quick, straightforward installation, the 2" nylon indicator seamlessly integrates onto standard large-bore adjustable choke bonnets, offering a lightweight, cost-effective, and essentially maintenance-free solution for critical flow monitoring.

Features & Benefits

• Accurate Flow Measurement: Provides a precise, easy-to-read visual indication of the adjustable choke's internal orifice size, calibrated up to a massive 2 inches (128/64ths).

• Industrial-Grade Nylon Construction: Built from heavy-duty engineered polymer that is 100% rust-proof and exceptionally resistant to harsh impacts and vibrations.

• Ultimate Chemical Resistance: Impervious to saltwater, frac fluids, and highly corrosive wellbore chemicals, drastically extending the component's lifespan.

• Non-Sparking Safety: The non-metallic construction eliminates spark risks during installation, adjustment, or accidental impacts in hazardous, combustible environments.

• High-Contrast Markings: Features deep, precision-molded increment markings designed to remain highly legible despite exposure to abrasive oilfield dirt and grease.

• Easy Installation: Designed for quick, tool-friendly mounting or replacement on standard large-bore, high-pressure adjustable choke assemblies.

Specifications & Technical Details

Applications

This 2" Nylon Choke Indicator is an ideal replacement part for operators managing large-bore flowline systems in highly corrosive or chemically aggressive environments. Typical applications include adjustable chokes mounted on extreme-duty choke and kill manifolds, massive frac flowback arrays, large-capacity surface well testing separators, and offshore production manifolds where non-sparking safety and absolute resistance to saltwater corrosion are strictly required.

Quality Assurance

Each nylon indicator undergoes strict quality control inspections, ensuring dimensional accuracy for a perfect fit on the heavy-duty choke bonnet, exact calibration of the 128/64ths measurement increments, and thorough material testing to guarantee maximum impact resistance and legibility in the field.
