O-ring NBR 11x1 mm

Applications & Industry Use

Advantages & Technical Data

Main Description

The O-ring 11x1 mm NBR 70 ShA - Pack of 1000 is a high-precision sealing component, featuring an inner diameter (ID) of 11 mm and a cross-sectional thickness (CS) of 1 mm, manufactured from nitrile rubber (NBR) with a hardness of 70 Shore A.

This metric O-ring dimension is recognized globally in industrial catalogs and technical searches under variants such as “O-ring 11x1”, “11x1 NBR O-ring”, “NBR 70 O-ring 11 mm”, “11 mm x 1 mm sealing ring”, or “oil resistant O-ring 11x1 mm”. Suppliers commonly list such O-rings with these labels, and they appear in digital parts catalogs and seal databases. The reference OR-11X1-NBR70 is one such standard coding used by manufacturers and distributors.

Because of its small cross-section (1 mm), this O-ring is particularly suited to fine tolerances, compact assemblies, and applications where minimal gap or tight sealing is required. Typical uses include hydraulic and pneumatic actuators, instrument housings, control valves, micro-pumps, fluid connectors, and sealing interfaces in low-flow circuits.

One of the main strengths of NBR (nitrile) elastomers is their resilience to oils, greases, and many hydrocarbons, making them a frequent choice in lubrication systems, engine components, fuel lines, hydraulic circuits, and industrial machinery. Many technical datasheets list NBR 70 ShA O-rings in such environments, highlighting their cost-effective balance between flexibility and chemical resistance.

In practical operation, the working temperature range is commonly -30 °C to +100 °C under moderate loads, with occasional tolerances for brief excursions beyond that region depending on fluid, dynamic stress, and back-up support. This product is generally applied in static sealing (stationary junctions) and light or minimal dynamic applications (vibration, micro-movements). The hard yet flexible 70 Shore A material helps resist compression set and extrusion, ensuring a stable seal over time.

This pack of 1000 O-rings is optimized for industrial customers, OEM suppliers, maintenance facilities, and high-volume users who seek consistency and bulk availability. You reduce procurement cycles and ensure continuity of spare parts in service inventory.

To avoid content overlap with existing catalog pages (e.g. on simmering.pl), this description places emphasis on bulk supply, specification clarity, and application contexts rather than generic material statements.

We also highlight logistical advantage: the stock is held in Warehouse & Store: Lublin, ul. Smoluchowskiego 1, building 4, with 24h shipping - fast and efficient order processing, which is a strong differentiator for clients in Poland and Central Europe.

FAQ

Q1: Will this O-ring 11x1 mm fit my groove?
A1: If your groove or housing inner diameter is ~11 mm and allowable cross-section is ~1 mm, this O-ring is suitable for a proper sealing fit.

Q2: What fluids and environments is NBR 70 ShA compatible with?
A2: Good resistance to mineral oils, greases, light fuels, and many hydrocarbons. Less suited for strong acids, ketones, ozone or UV-intensive conditions.

Q3: What is the operating temperature range?
A3: Typically between -30 °C and +100 °C under normal pressure and static/dynamic conditions. Brief periods beyond may be tolerated in favorable setups.

Q4: Is this O-ring suitable for dynamic (moving) sealing?
A4: It performs best in static sealing. For low-motion applications (vibrations, small oscillations) it may work, but for high-speed or reciprocating motion, dedicated dynamic seals are recommended.

Q5: When can I receive my order?
A5: We stock this product in Lublin. From Warehouse & Store: Lublin, ul. Smoluchowskiego 1, building 4, we offer 24h shipping - fast and efficient order processing, so many orders are delivered next business day.
