Frequently Asked Questions About Pneumatic Seals
1. What is a pneumatic seal?
A pneumatic seal is a device used to prevent air or gas leakage in systems powered by compressed air. It ensures airtight sealing in cylinders, valves, and actuators.
2. What is a pneumatic seal used for?
Pneumatic seals are used in air-powered equipment to maintain pressure and prevent contamination. They enable smooth and efficient motion in pneumatic cylinders and tools.
3. What are pneumatic seals made of?
Pneumatic seals are typically made from materials like NBR, PU, FKM, or PTFE. These materials offer resistance to wear, friction, and temperature for reliable air sealing performance.
4. Where to buy pneumatic seals?
You can purchase pneumatic seals from professional suppliers like Hengoseal.com, which offers rod seals, piston seals, and custom pneumatic sealing solutions at factory prices.
5. How to seal pneumatic fittings?
To seal pneumatic fittings, use PTFE tape or thread sealant on the male threads before tightening. This prevents air leaks and ensures a secure connection in the air system.
6. What is a good pneumatic seal?
A good pneumatic seal resists air leakage, operates smoothly with minimal friction, and lasts under repeated cycles. High-quality materials and precise fit are key for optimal performance.
