Industrial O-Ring 380.6 x 3.53 mm CR - High-Performance Chloroprene Rubber Seal for Hydraulic and Pneumatic Systems

Applications

The metric O-Ring 380.6x3.53 mm produced from CR (chloroprene, neoprene) is designed for demanding industrial sealing applications. This rubber gasket and sealing ring excels in static- or light-motion environments across hydraulic systems, pneumatic devices, large bore assemblies, flanged joints and industrial equipment glandings. Its dimension (ID 380.6 mm, cross-section 3.53 mm) accommodates large-diameter bores and enables use in heavy-duty installations where precise industrial sealing components are required. With excellent chemical resistance, high durability and suitability for applications in hydraulics and pneumatics, this O-ring supports procurement teams seeking robust and reliable technical sealing components for production, maintenance and MRO applications.

Advantages

• High durability & chemical resistance: The CR (chloroprene) compound resists ozone, weathering, moderate oils and greases, offering extended service life compared to standard elastomers in demanding conditions.

• Large metric size (380.6x3.53 mm): Ideal for installations with wide-bore gasket glands or custom flanged applications, where standard sizes are not sufficient.

• Designed for industrial rubber gasket applications: This sealing ring meets the needs of B2B users—manufacturers, service providers and industrial buyers—seeking quality uszczelnienie techniczne in hydraulics and pneumatics.

• Ease of supply chain integration: Supplied in standard stock format, the O-ring is suited for quotas, maintenance kits and procurement planning.

• Local stock and fast logistics: Available from our warehouse in Lublin, ul. Smoluchowskiego 1, building 4, with 24h delivery for B2B orders, supporting uptime and rapid replacement in critical systems.

FAQ

Q1: What makes chloroprene (CR) suitable for large-diameter O-rings like 380.6x3.53 mm?
A: CR offers enhanced resistance to ozone, weathering, moderate oil and grease exposure. For large-bore gland applications where durability matters and static sealing suffices, CR is a reliable choice.

Q2: Can this O-ring be used in hydraulic or pneumatic media?
A: Yes. While CR is less specialised than fluorocarbon rubbers, it is commonly used in general hydraulic and pneumatic applications, especially where moderate oil/grease resistance and large sizes are required.

Q3: Is the 380.6x3.53 mm format standard, and how to verify fit?
A: This size corresponds to metric gland dimensions. Verify that the internal gland diameter is ~380.6 mm and the groove accommodates CS 3.53 mm cross-section. Correct fit ensures optimal sealing and life-cycle performance.

Q4: Is this O-ring suitable for dynamic (moving) applications?
A: This model is intended primarily for static sealing or slight movement. In high-motion scenarios (such as fast reciprocation or rotation), you should review bearing/gland design and consider specialised elastomers or sealing solutions.

Q5: How quickly is this product available and where is it stocked?
A: The product is stocked in our warehouse in Lublin (ul. Smoluchowskiego 1, building 4) and is available for 24h delivery—which supports fast procurement and minimal downtime for industrial users.
