High Temperature O-Ring Kits — Polypac High-Performance Sealing Solutions
High Temperature O-Ring Kits — Reliable Sealing for Extreme Conditions
About Polypac
Polypac is a scientific and technical hydraulic seal manufacturer and oil seal supplier founded in 2008. Our custom rubber ring and O-ring factory spans more than 10,000 m² with 8,000 m² of production space. We pair long-term academic partnerships with advanced production and testing equipment to develop seals and sealing materials for specialized working conditions.
Why Choose High Temperature O-Ring Kits
High Temperature O-Ring Kits from Polypac are engineered to maintain sealing integrity under elevated temperatures, aggressive media, and cyclic thermal stress. Our kits reduce downtime and maintenance costs by providing material combinations and tolerances optimized for long-term performance in extreme environments.
Materials & Customization
We offer O-rings in FFKM (perfluoroelastomer), FKM (fluoroelastomer), silicone, EPDM, NBR, and PTFE-based options including filled PTFE variants. Polypac specializes in custom formulations and sizes, enabling tailored kits for applications that require chemical resistance, low permeability, or extreme temperature stability.
Quality & Testing
Our production lines and laboratory testing meet rigorous quality standards. From dimensional control and hardness testing to thermal aging and media compatibility assessments, each High Temperature O-Ring Kit undergoes strict inspection to ensure consistent reliability and compliance with customer specifications.
Typical Applications
Polypac High Temperature O-Ring Kits serve petrochemical processing, aerospace, power generation, valves and pumps, compressors, and specialty manufacturing. They are ideal for sealing in high-heat manifolds, steam systems, high-pressure hydraulic circuits, and corrosive process environments.
Ordering, Kits & Technical Support
We deliver configurable kits that include multiple sizes, material options, and part numbers for rapid replacement and inventory management. Polypac provides technical consultation, sample testing, and OEM/ODM services to design kits that meet your operational and regulatory needs. Contact our engineers for material selection, custom tooling, and lead-time estimates.
Commitment to Performance
Polypac’s combined R&D experience, production capacity, and international collaboration ensure that every High Temperature O-Ring Kit is backed by science-driven design and proven manufacturing practices. Choose Polypac for dependable sealing solutions in the most demanding conditions.

What is the difference between NBR and FKM materials?
NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F). FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.
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 important is surface finish on the metal parts that contact the seal?
Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.
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.
