About Buffer Seal

With the support of our skilled employees, we are manufacturing, supplying, and exporting Buffer Seal. It is usually paired for applications with another rod seal, such as a U-cup style seal. Such kinds of seals are usually used in rod applications for absorbing pressure fluctuations, under high-load conditions. Hence, it contributes to the increasing lifespan of the rod seal. In addition, it is capable of maintaining sealing contact in sliding motion between piston rod, and cylinder head. Further, Buffer Seal is a primary seal in tandem sealing configuration, which allows it to withstand pressure peaks from the system.

Engineered for Demanding Conditions

Our buffer seal is specifically built for applications with high pressure and potential wear. With a tensile strength of 15-20 MPa and resistance to extreme operating environments, it offers dependable sealing for hydraulic systems. Advanced materials like polyurethane or nitrile rubber ensure reliable performance over a wide temperature range.

Versatile Sizes and Customization

Standard dimensions range from 20 mm to 250 mm diameter, with widths up to 50 mm. Both standard and custom sizes are available, accommodating diverse cylinder types. The seals ring profile and smooth finish facilitate easy press-fit installation into a wide array of cylinder gland grooves.

Reliable Sealing for Industrial Applications

This buffer seal is the choice of manufacturers, exporters, and industrial users across India. Its strong chemical resistance, low water absorption, and ability to withstand high compression set it apart in hydraulic and pneumatic machinery, ensuring reduced maintenance and longer service life.

FAQs of Buffer Seal:

Q: How is the Buffer Seal installed in hydraulic cylinders?

A: The Buffer Seal is designed for press-fit installation directly into the gland or cylinder groove. Its circular profile and precision tolerances (0.1 mm) ensure a secure, leak-resistant fit that is simple to insert using standard tools.

Q: What materials are used in the Buffer Seal, and what are their benefits?

A: Manufactured from high-quality polyurethane (PU) or nitrile rubber (NBR), the Buffer Seal offers excellent resistance to wear, extrusion, oils, fuels, and hydraulic fluids. These materials deliver long service life and robust performance under high pressures.

Q: Where can the Buffer Seal be used?

A: Buffer Seals are widely used in hydraulic cylinders, pneumatic machinery, and industrial automation systems. Their versatility makes them suitable for various industrial, manufacturing, and mechanical environments where hydraulic sealing is critical.

Q: What are the main advantages of using this Buffer Seal?

A: Key benefits include high pressure resistance (up to 400 bar), wear and extrusion resistance, reliable prevention of fluid leakage, and compliance with international ISO standards. This leads to low maintenance and increased operational reliability.

Q: Does Buffer Seal comply with international standards?

A: Yes, the seal conforms to ISO 5597 and ISO 7425 standards, ensuring compatibility and quality for global industrial applications.

Q: Can I order Buffer Seals in custom sizes or get OEM service?

A: Yes, both standard and customized sizes are available, and OEM manufacturing services can be provided to meet specific requirements for various machinery and industries.
