FAQ's of Rubber Seals:

Q: How can rubber seals be customized to fit specific machinery requirements?

A: Rubber seals are available in a variety of shapes and sizes, including O-ring, D-ring, square, rectangular, and unique profiles created through custom extrusion. Dimensions, thickness, and width can be tailored to match precise engineering designs, ensuring an optimal fit and reliable sealing for your machinery or equipment.

Q: What benefits do EPDM and Silicone rubber seals offer for outdoor and high-ozone environments?

A: EPDM and Silicone rubber seals provide excellent resistance to ozone, UV radiation, and weathering. These properties make them particularly suitable for applications exposed to outdoor elements, where long-term durability and protection against environmental degradation are crucial.

Q: Where are these rubber seals typically used and what operating media are they compatible with?

A: These seals are widely applied in automotive, machinery, plumbing, hydraulics, and pneumatic systems. They function effectively with air, water, oil, and mild chemicals, ensuring secure sealing in diverse industrial and mechanical environments.

Q: When should I choose NBR or Neoprene rubber seals over other materials?

A: NBR (Nitrile) and Neoprene are recommended when moderate ozone resistance is sufficient, and there is a need for good oil and chemical resistance. These materials are particularly effective in environments where oil, hydraulic fluids, or moderate chemicals are present.

Q: What is the manufacturing process and lead time for these seals?

A: Our seals are manufactured using advanced molding and extrusion processes that ensure high accuracy and consistent surface finish. Standard and custom orders are fulfilled within 7 to 15 working days, depending on the order quantity and customization requirements.

Q: How do rubber seals maintain their performance under varying pressure and temperature conditions?

A: With a working pressure of up to 10 bar and the ability to withstand temperatures from -40C to 200C (depending on the rubber type), these seals maintain their elasticity and sealing efficiency. Their low compression set and high elongation at break contribute to long-term performance under fluctuating conditions.
