Piston Seals Built for Tight Fit, Low Leakage, and Hard Working Cylinders

Off-the-shelf piston seals often fail where pressure spikes, heat, and poor gland fit start working against the cylinder. Seal Turning Solutions manufactures piston seals for demanding hydraulic and industrial applications, using the right material and profile for the job. We also modify pistons and related components so the seal does not just fit - it performs under load.

Piston seals are only as reliable as the machining, material choice, and gland dimensions behind them. Seal Turning Solutions makes custom seals and bushes for hydraulic, automotive, and industrial machinery systems where leakage, drag, or premature wear can stop production fast. If a standard part is not sealing correctly, we can manufacture a replacement piston seal and adjust the surrounding component to restore proper contact and performance. Our work includes polyurethane, PTFE, nylon, carbon, nitrile, Viton, EPDM, and steel solutions, plus related modifications, bearing pressing, and precision parts for complete cylinder support.

What you get

• Custom Material Selection — We match piston seals to pressure, temperature, fluid type, and wear conditions so the seal keeps its shape and sealing edge in service.
• Precision Component Modifications — We modify pistons, glands, and related parts to correct fit issues that cause bypass, friction, or early seal failure.
• Built for Industrial Duty — Our piston seals are made for hydraulic and machinery environments where downtime is expensive and reliability matters every cycle.
• Complete Seal Support — We also supply bushes, cylinder kits, chrome shafts, rubber bellows, and rod ends to support the full assembly, not just one part.

How it works

1. We inspect the worn piston, gland, or sample seal to confirm the dimensions, wear pattern, and application conditions that the replacement must handle.
2. We select the most suitable material and profile, then manufacture the piston seal or matching component to the required specification.
3. We machine or modify the piston and related parts where needed so the seal seats correctly and the assembly runs smoothly.

Frequently asked questions

Q: What are piston seals used for?
A: Piston seals keep hydraulic or pneumatic fluid from passing across the piston inside a cylinder, which allows the system to build and hold pressure. They are critical in equipment where smooth movement and controlled force are needed.
Q: Can you make piston seals from different materials?
A: Yes, we work with polyurethane, PTFE, nylon, carbon, nitrile, Viton, EPDM, and steel depending on the application. The material is selected based on pressure, heat, movement, and the fluid the seal will contact.
Q: Do you only make new piston seals?
