Oil Resistant Rubber O-Rings by Polypac
Oil Resistant Rubber O-Rings by Polypac
High Quality oil-resistant materials
Polypac's Oil resistant rubber O-rings are formulated from industry-proven elastomers including NBR (Nitrile), FKM (Viton), silicone, EPDM, and FFKM. Each compound is optimized for hydrocarbon resistance, compression set performance, and temperature stability to ensure long service life in oil, fuel, and lubricant environments.
Advanced manufacturing and precision tolerances
Our 10,000+ m2 custom rubber ring and O-ring factory uses automated molding, CNC finishing, and modern inspection equipment to deliver tight dimensional control. Consistent cross-sectional accuracy and surface finish reduce leak risk and simplify installation in hydraulic cylinders, pumps, and rotating equipment.
Rigorous testing and quality assurance
Polypac enforces ISO-aligned testing protocols including hardness, tensile, elongation, compression set, and fluid swell evaluations. We combine in-house labs with collaborative research from universities to validate oil resistance, accelerated aging, and real-world performance under high-pressure and high-temperature conditions.
Custom solutions for special working conditions
When standard O-rings fall short, Polypac offers tailored compounds and geometries: low-permeability blends, filler-reinforced PTFE combinations, and custom durometers. We support small runs to high-volume production and provide engineering guidance for groove design and material selection.
Wide application spectrum
Our oil resistant rubber O-rings serve hydraulic systems, automotive powertrains, industrial compressors, marine equipment, and oilfield tools. Material choice and quality control ensure reliability in both static and dynamic sealing scenarios subject to oils, fuels, and aggressive lubricants.
Why choose Polypac
Founded in 2008, Polypac blends decades of seal manufacturing expertise with R&D partnerships and advanced equipment. As a leading oil seal supplier, we focus on performance, traceability, and rapid prototyping—delivering durable O-rings that lower downtime and total cost of ownership.

How can I prevent seal damage during installation?
Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.
When should I use a spring-energized seal instead of a standard elastomeric seal?
Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.
What is the difference between a static seal and a dynamic seal?
A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
What does "AS568" mean?
AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.
