Hydraulic O-Ring Kit FACE ORFS Fittings 155 Pieces - Durable Nitrile

In this review the Hydraulic O-Ring Kit FACE ORFS Fittings 155 Pieces is evaluated for hydraulic and pneumatic technicians who need a compact, ready-to-use assortment of ORFS seals. The bottom line: this kit is most valuable for people who repair or maintain hydraulic systems and need a selection of robust, oil-resistant O-rings in one portable case. The reviewer found the Buna-N 90 durometer material and the printed sizing chart in the case to be the single biggest conveniences that make field work faster and reduce repeat trips for missing parts.

Key Features

• Material: The Buna-N 90 durometer NBR construction provides excellent oil resistance and strong tear resistance for hydraulic environments.
• Temperature range: Rated for continuous use to about 212F and intermittent use to 250F while remaining usable down to -30F.
• Pressure suitability: The harder, denser 90 durometer composition is better suited for higher pressure applications where softer seals would extrude.
• Assortment: Includes eight common FACE ORFS sizes with a total of 155 pieces, covering Dash 4 through Dash 24 for quick parts replacement.
• Storage case: The multi-compartment plastic carrying case is printed with a sizing chart for easy identification and fits neatly into a toolbox or vehicle.

Who It's For

This kit is aimed at hydraulic technicians, farmers, fleet maintenance crews, and small shops that service hydraulic pumps, cylinders, valves, and fittings. The assortment of Dash 4 to Dash 24 sizes and higher durometer material make it practical for frequent field repairs and preventive maintenance where ORFS face seals are common.

It is not intended for applications that require specialty elastomers such as Viton for high chemical resistance, or for users who need metric-size O-rings or extremely soft seals for low-pressure static applications. Professionals with varied material requirements should supplement this kit with other compound types.

Pros & Cons

Pros

• Durable Buna-N 90 durometer material resists oil, weathering, and tearing for reliable sealing.
• Large assortment of common FACE ORFS sizes (155 pieces) reduces downtime for repairs.
• Compact carrying case with printed sizing chart simplifies selection during service calls.

Cons

• Limited to Buna-N NBR; not suitable where fluorocarbon or silicone elastomers are required for extreme chemical or high-temperature exposure.
• Sizes are ORFS dash numbers only; users needing metric or non-ORFS standards must look elsewhere.
