O-Ring 17x4 NBR 70 Shore A

O-Ring 17x4 NBR 70 Shore A - 100 pcs

O-Ring 17x4 NBR 70 Shore A is an elastomeric sealing ring with a 17 mm inside diameter and 4 mm cross-section. It is manufactured from NBR - Nitrile Butadiene Rubber - with a nominal hardness of 70 Shore A. This product is supplied in a pack of 100 O-rings.

O-Ring 17x4 NBR 70 Shore A - Dimensions

Nominal size: 17x4 mm

Inside diameter d1: 17 mm

Cross-section: 4 mm

Nominal outside diameter: 25 mm

Material: NBR - Nitrile Butadiene Rubber

Hardness: 70 Shore A

Pack quantity: 100 pcs

What Does O-Ring 17x4 Mean?

The 17x4 mm designation specifies:

17 mm - inside diameter

4 mm - cross-section diameter

The nominal outside diameter is calculated as:

17 + 2 x 4 = 25 mm

The nominal geometry is therefore:

ID: 17 mm

CS: 4 mm

OD: 25 mm

NBR 70 Shore A Material

The O-ring is manufactured from:

NBR - Nitrile Butadiene Rubber

Nominal hardness:

70 Shore A

NBR is widely used as an elastomeric sealing material, particularly for applications involving many mineral oils, greases and selected hydraulic fluids.

Compatibility should always be verified for the specific medium, temperature and operating conditions.

O-Ring 17x4 NBR Applications

O-Rings 17x4 NBR can be used as sealing elements in appropriately designed assemblies, including:

Machinery and equipment

Hydraulic components

Pumps and valves

Mechanical assemblies

Maintenance and repair

Industrial service applications

Suitability for a specific application depends on the groove design, sealing medium, pressure, temperature and actual operating conditions.

Pack of 100 O-Rings

This product includes:

100 pcs O-Ring 17x4 NBR 70 Shore A

The 100-piece pack provides a practical quantity for workshops, maintenance departments, repair operations and users who require a working stock of one specific O-ring size without purchasing a large bulk package.

How to Select an O-Ring 17x4

When selecting an O-ring, verify:

Inside diameter

Cross-section

Elastomer material

Hardness

Operating medium

Operating conditions

Seal groove geometry

Matching the 17x4 mm dimensions alone does not establish complete technical interchangeability between O-rings manufactured from different materials or compounds.
