O-Ring 27.5x1.5 mm NBR

Applications

The O-Ring 27.5x1.5 mm NBR is a compact and precise sealing component tailored for industrial maintenance, OEM production and service-spare programmes. Constructed from nitrile rubber (NBR), this sealing ring is engineered for systems exposed to oils, greases and moderate hydraulic or pneumatic pressure. With its inner diameter of 27.5 mm and cross-section of 1.5 mm, it fits standard grooves in pumps, valves, actuators, and other fluid-power equipment where high durability and reliable static sealing are required. Ideal for tasks such as fluid power systems, machine tool lubrication units, hydraulic spares and pneumatic valves.

Advantages

• Robust oil and lubricant resistance - The NBR elastomer supports exposure to mineral oils, maintenance greases and many industrial hydraulic fluids, ensuring long-term sealing performance.

• Compact dimension for precise fit-up - With 27.5 mm ID x 1.5 mm CS, this gasket supports tight gland designs, reducing leakage potential while enabling efficient inventory management of small sealing rings.

• Versatile industrial use - Appropriate for static sealing and moderate dynamic applications (e.g., low-speed pistons, rotary joints with light movement), this ring addresses both manufacturing and maintenance sectors.

• Engineered for B2B procurement - Designed for technical buyers and production managers, this sealing ring supports streamlined procurement workflows, stock-keeping and rapid service-replenishment.

• Local availability with rapid dispatch - Stock located at our warehouse in Lublin (ul. Smoluchowskiego 1, building 4) with 24h delivery capability ensures minimal downtime and fast order fulfilment.

FAQ

Q1: What does “27.5x1.5 mm” represent for this O-Ring?
A1: The dimension indicates a 27.5 mm inner diameter and a 1.5 mm cross-section (thickness). Correct dimensioning ensures compatibility with the gland and maintains sealing integrity.

Q2: What are the benefits of NBR material in this context?
A2: NBR (nitrile rubber) provides strong resistance to oils, greases and many hydraulic fluids, making it a standard choice for rubber gaskets and industrial sealing rings in fluid-power applications.

Q3: Is this O-Ring suitable for dynamic applications?
A3: Yes - it can be used for moderate dynamic sealing tasks (e.g., slow reciprocation or light rotary movement) provided correct groove design and lubrication are in place. For high-speed dynamic applications, material evaluation is recommended.

Q4: What is the recommended temperature range for this seal?
A4: Under standard conditions, the working range is approximately -30 °C to +100 °C. Exceeding these limits or using aggressive media may require alternative elastomer types.

Q5: How quickly can this product be shipped for industrial maintenance?
A5: The product is stocked and ready for dispatch from our Lublin warehouse. With operational order processing, a 24 h shipping turnaround is available for industrial buyers and procurement teams.
