Nitrile Hydraulic Wiper Seal

Nitrile Hydraulic Wiper Seal (NBR)

This Nitrile (NBR/Buna-N) hydraulic wiper seal is engineered to exclude contaminants — dirt, dust, moisture, and debris — from hydraulic cylinder rod systems. The flexible wiping lip maintains consistent contact with the rod surface across a broad temperature range, protecting internal seals and extending the service life of hydraulic cylinders in demanding industrial and mobile equipment applications.

Key Features

• Material: Nitrile rubber (NBR/Buna-N) — excellent resistance to petroleum-based hydraulic oils
• Function: Rod wiper / excluder seal for hydraulic cylinders
• Flexible lip profile maintains consistent rod contact for reliable contaminant exclusion
• Good abrasion resistance for extended service life
• Cost-effective solution for standard hydraulic cylinder applications
• Available in a range of bore and rod sizes

Typical Applications

• Industrial hydraulic cylinders
• Mobile equipment (construction, agriculture, material handling)
• Machine tools and presses
• Lifting and clamping systems

Operating Parameters

• Temperature Range: -40°F to +212°F (-40°C to +100°C)
• Media: Mineral-based hydraulic oils, petroleum fluids
• Not recommended for: phosphate ester fluids, ketones, or strong acids

Sold as individual seals. Verify bore and rod dimensions before ordering to ensure proper fit.
