Carbide Choke Parts We Quote
We supply tungsten carbide choke trim made to your drawing, sample or part number, in the sizes and geometries your chokes use.
Choke Beans and Orifices
Fixed and positive choke beans with precision-ground bores that hold their size against sand and high-velocity flow.
Stems and Tips
Adjustable choke stems and carbide tips ground to your profile for consistent flow control and longer service life.
Seats and Seat Rings
Matching carbide seats and rings for a clean shutoff and less washout at the seat face.
Sleeves and Liners
Carbide wear sleeves and liners that protect the choke body where erosion hits hardest.
Built for Erosive, High-Pressure Flow
Chokes take the full force of the pressure drop. Produced sand and high-velocity fluid erode steel trim quickly, which changes the flow rate and forces early replacement.
Fine-grain tungsten carbide resists that abrasion far better than hardened steel. We work in a 12% cobalt grade for toughness and impact resistance, and a 6% nickel grade for better corrosion resistance in wet or corrosive service.
Our shop handles centerless, surface and Blanchard grinding plus 5-axis CNC grinding, so bores, tapers and seat faces are finished to your tolerances.

Tungsten Carbide Choke Questions
What do you need to quote a tungsten carbide choke part?
A drawing or photo with dimensions, the choke type and size, the quantity you need, and the service conditions: pressure, flow rate, sand content and fluid. If you do not have a drawing, the part number or a worn part we can measure also works.
Should I choose a cobalt or nickel binder grade?
The 12% cobalt grade is the usual choice for toughness and abrasion resistance. The 6% nickel grade holds up better where corrosion is a concern, such as wet or corrosive production. Tell us about the application and we will recommend a grade.
How long does it take to get custom carbide choke parts?
Custom parts are typically delivered in less than four weeks. Lead time depends on the part, the quantity and the grinding involved, and we confirm it with your quote.
Can you make carbide choke parts for other manufacturers' chokes?
Yes. We make parts to your drawing or to the dimensions of an existing part, so you can source replacement choke trim without waiting on the original manufacturer.
