Applications

Industries Relying on Our Precision Balls

Check Valves

PTFE and PEEK check valve balls for chemical dosing pumps, backflow prevention, and one-way flow control — chemically inert and non-stick surface prevents media buildup.

Flow Meters

Precision-grade PEEK and PVDF balls for rotameters and variable-area flow meters — consistent specific gravity and sphericity for accurate flow measurement.

Oil & Gas Downhole Tools

PEEK and PTFE frac balls for hydraulic fracturing, well completion ball drop systems, and downhole sliding sleeve actuation — high-pressure resistant, chemically inert to frac fluids and acidizing chemicals.

Bearings & Ball Valves

High-grade PTFE and PEEK balls for corrosion-resistant bearings and full-port ball valves in chemical plants, water treatment, and food processing equipment.

Common Questions

Precision Ball Manufacturing FAQ

What types of PTFE balls do you manufacture? +

We manufacture a wide range of PTFE balls including: PTFE check valve balls for chemical dosing pumps, PTFE ball valve balls for corrosive fluid shut-off, PTFE frac balls and well completion balls for oil & gas downhole fracturing, PTFE float balls for level sensors and tank gauges, solid PTFE bearing balls for low-friction rotary applications, PTFE flow meter balls for rotameters and variable-area meters, PTFE non-return valve balls for backflow prevention, and custom-diameter PTFE balls to your specification. Diameters from 2mm to 150mm, grades G10 to G100. PEEK balls also available for high-temperature, high-pressure, and high-strength downhole applications.

What ball grade do I need for my application? +

G10-G25 (sphericity 0.001-0.0025mm) is recommended for precision instruments, flow meters, and high-performance check valves. G50-G100 (sphericity 0.005-0.01mm) is suitable for general industrial ball valves, bearings, and fluid handling. Our engineers will help you select the right grade based on your sealing and functional requirements.

Can you produce balls in custom diameters not listed in standard sizes? +

Yes. We precision-grind balls to any diameter between 2mm and 150mm — no need to compromise on a "close enough" standard size. Simply specify your exact diameter and tolerance, and we'll machine to your requirement.

PTFE vs PEEK — which material is better for check valve balls? +

PTFE is the best choice for universal chemical resistance and low-friction sealing — ideal for most chemical check valve applications. PEEK is preferred when the ball sees high mechanical loads, elevated temperatures (up to 260°C), or steam service. Our engineers will recommend based on your specific media, pressure, and temperature profile.

What is your minimum order quantity for precision balls? +

We support prototype orders starting from 1 piece for design validation. Production quantities start at 100 pieces per size, with volume pricing discounts at 1,000+ and 10,000+ piece quantities. We also offer consignment stock programs for repeat orders.

Can you supply PTFE and PEEK balls for oil & gas frac applications? +

Yes. We manufacture PEEK and PTFE frac balls for hydraulic fracturing operations, ball-activated sliding sleeves, and downhole well completion tools. Our PEEK frac balls offer high compressive strength for seating pressures up to 70 MPa, excellent chemical resistance to frac fluids and acidizing chemicals, and consistent sphericity for reliable ball-to-seat sealing. PTFE frac balls provide superior chemical inertness for corrosive downhole environments. Custom diameters and tight tolerance grades available — contact Leon with your frac ball specification.

Do you provide sphericity and surface finish inspection data? +

Yes. Every production batch includes CMM sphericity measurement reports and surface roughness (Ra) data. For critical applications, we can provide individual ball inspection certificates with full dimensional traceability.
