Polypac FDA O-Ring Kits — Certified Sealing Solutions
Polypac FDA O-Ring Kits — Certified Sealing Solutions
Polypac provides High Quality FDA O-Ring Kits designed for hygienic, safety-critical environments such as pharmaceuticals, food processing, and medical device manufacturing. Backed by a 10,000 m2 facility and advanced production and testing equipment, our kits combine FDA-compliant materials, traceable manufacturing, and flexible packaging to simplify maintenance and ensure regulatory confidence.
Materials & Compatibility
Our FDA O-Ring Kits include a range of elastomers: NBR, FKM, silicone, EPDM, and high-purity FFKM. Each material is selected for chemical resistance, temperature range, and biocompatibility. Polypac collaborates with universities and research institutes to validate compound formulations so your kit meets both FDA guidance and real-world performance requirements.
Custom Kits for Special Conditions
Polypac specializes in custom rubber ring and O-ring kits tailored to special working conditions. Choose from multiple sizes, durometers, and packaged sets that include PTFE-based seals or filled PTFE options for abrasive or high-wear systems. Custom labeling, lot traceability, and sterilizable packaging are available to meet your operational and regulatory needs.
Quality Assurance & Testing
Quality is central to every FDA O-Ring Kit. Our factory uses industry-leading production and inspection equipment, supported by long-term R&D partnerships. We perform dimensional control, compression set, extractables testing, and hydraulic sealing performance checks to ensure each kit meets stringent standards and provides documented traceability for audits.
Applications & Benefits
Designed for critical environments, these kits reduce downtime, lower contamination risk, and streamline preventive maintenance. Common applications include pharmaceutical processing lines, food and beverage equipment, laboratory instruments, and medical device assembly. Polypac kits deliver consistent sealing performance and cost-effective inventory management.
Ordering & Technical Support
Polypac offers fast lead times, sample kits, and expert technical support to optimize seal selection and installation. Whether you need standard FDA O-Ring Kits or bespoke solutions, our engineers assist with material choice, sizing, and validation support to ensure compliance and long-term reliability.

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.
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.
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.
Can I reuse a seal?
We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.
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.
