Viton O-Ring Kits — Polypac High-Performance Seal Solutions
Viton O-Ring Kits by Polypac — Reliable FKM Seal Solutions
Overview
Polypac Viton O-Ring Kits provide ready-to-use assortments of FKM (Viton) O-rings engineered for demanding applications. Each kit contains multiple sizes and hardnesses to cover maintenance, emergency repairs, and OEM assembly needs. Our kits are optimized for performance, longevity, and ease of installation across hydraulic, pneumatic, and fluid-handling systems.
Materials & Performance
Viton (FKM) is renowned for exceptional resistance to heat, fuels, oils, and a wide range of aggressive chemicals. Polypac Viton O-Ring Kits include compounds tailored for temperature ranges, compression set resistance, and specific media compatibility. Available formulations and hardness options ensure reliable sealing from -20°C to +200°C (and higher with specialty grades).
Customization & Manufacturing Capability
As a leading seal manufacturer, Polypac operates a 10,000+ m² facility with 8,000 m² production space and advanced mixing, molding, and testing equipment. Founded in 2008 with PTFE expertise, we now produce custom Viton O-Ring Kits alongside NBR, FFKM, silicone, EPDM, and specialty PTFE-filled seals. Custom sizes, colors, packaging, and client-specific compound development are standard services.
Quality Assurance & Testing
Polypac maintains stringent quality control with industry-leading testing: tensile strength, hardness, compression set, aging, and chemical compatibility. Our long-term collaborations with universities and research institutions ensure continual material improvements and documented performance—ideal for safety-critical and regulated industries.
Applications & Industries
Viton O-Ring Kits serve automotive, aerospace, chemical processing, oil & gas, hydraulics, pumps, valves, and industrial maintenance. Kits reduce downtime by providing correct-fit FKM seals for routine service and field repairs where chemical and thermal resistance is essential.

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 purpose of the metal spring in a rotary shaft seal?
The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
How do I choose the right material for my sealing application?
Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.
Why did my O-ring fail prematurely?
Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.
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.
