Features & Applications

Benefits & Technical Data

Main Description

The O-Ring 32x3 mm NBR 70 ShA (Pack of 100) is a precision sealing ring designed for demanding industrial and hydraulic applications. It features an internal diameter of 32 mm and a cross-section or cord thickness of 3 mm, molded from nitrile rubber (NBR) with a hardness of 70 Shore A.

This combination of dimensions and material is widely searched and utilized in global markets under query terms like “O-ring 32x3”, “32x3 NBR O-ring”, “NBR 70 ShA sealing ring”, “oil resistant O ring 32x3 mm”, “metric O-ring 32 by 3”, or “industrial O-ring pack 100”.

Thanks to the NBR compound, this O-ring package offers strong resistance to oils, greases, and many hydrocarbons, making it suitable for lubrication circuits, engines, pumps, fuel systems, hydraulic controls, valves, and general-purpose sealing tasks. Its working temperature window typically ranges from -30 °C to +100 °C under normal conditions (depending on pressure, fluid type, and dynamic stresses).

With a hardness of 70 ShA, the O-ring maintains enough elasticity to conform to mating surfaces while resisting permanent deformation and extrusion under pressure. This makes it well-suited for static sealing and moderate dynamic use (e.g., light reciprocating motion, vibration).

Because the pack contains 100 pieces, it is ideal for industrial users, maintenance shops, and OEM supply chains. This bulk quantity ensures that replacements are always on hand, reducing downtime due to missing components.

FAQ

Q1: Will this O-ring 32x3 mm fit my application?
A1: If your groove or housing has an internal diameter close to 32 mm and accepts a cord thickness (cross-section) of ~3 mm, then this O-ring is appropriate.

Q2: What fluids and conditions is NBR 70 ShA compatible with?
A2: NBR is commonly resistant to mineral oils, greases, petroleum-based fluids, and many hydraulic oils. It performs well in typical temperature ranges (-30 °C to +100 °C).

Q3: Is this O-ring usable in dynamic conditions (moving parts)?
A3: Its primary design is for static sealing. In low-speed, low-amplitude motion (vibrations, mild reciprocation) it may work, but for heavy dynamic sealing, specialized seals are recommended.

Q4: Why order a pack of 100?
A4: A 100-piece pack is ideal for industrial users and service centers — it ensures you always have spares, reduces ordering frequency, and lowers per-piece cost.

Q5: How quickly can I get it?
A5: This product is kept in stock at our Warehouse & Store in Lublin (ul. Smoluchowskiego 1, building 4). We offer 🚚 24h shipping - fast dispatch, so many customers receive their order the next business day.
