Polypac specializes in developing custom sealing solutions for a wide range of demanding environments—from ultra-high temperature and pressure to extremely low temperatures and corrosive environments. Our R&D team, advanced materials, and precision manufacturing processes ensure optimal sealing performance in any application.
1. Construction & Heavy Equipment
The Challenge
Extreme shock pressures, abrasive contaminants, wide temperature swings, and demanding duty cycles that lead to frequent seal failure and costly downtime on excavators, bulldozers, and cranes.
Our Solution
High-Pressure Piston & Rod Seals.
How it Works
Our LBH seals provide robust, bidirectional sealing in hydraulic cylinders, offering superior extrusion resistance to handle pressure spikes beyond 40 MPa.
For the rod side, GSF seals with PTFE and a metal spring ensure zero leakage and keep contaminants out.
The Benefit
Extended component life, reduced hydraulic fluid consumption, and increased machine availability, keeping your projects on schedule and within budget.
2. Automotive & Transportation
The Challenge
Sealing for high-speed rotation, exposure to synthetic oils and fuels, extreme engine temperatures, and the need for absolute reliability in safety-critical systems like brakes and steering.
Our Solution
High-Performance Rotary Shaft Seals & Engine Seals.
How it Works
Our oil seals retain lubricant in gearboxes, axles, and wheel hubs while excluding dirt and water.
Our FKM O-rings withstand under-the-hood temperatures and aggressive engine fluids.
The Benefit
Enhanced vehicle reliability, prevention of lubricant leakage, and protection of critical bearings and components for improved safety and longevity.
3. Food, Beverage & Pharmaceutical (FDA/USP Class VI Compliant)
The Challenge
Requiring non-toxic, odorless, and tasteless seals that can withstand repeated CIP/SIP (Clean-in-Place/Sterilize-in-Place) processes with steam, hot water, and aggressive cleaning agents without degrading.
Our Solution
Certified Hygienic Seals.
How it Works
Our Silicone and EPDM compounds are certified to FDA and USP Class VI standards, offering excellent resistance to steam, ozone, and cleaning chemicals.
PTFE provides pure inertness for ultra-sensitive processes.
The Benefit
Guaranteed product purity, compliance with strict health regulations, and reduced risk of microbial harborage in processing and packaging lines.
4. Chemical Processing & Industrial Manufacturing
The Challenge
Sealing aggressive solvents, strong acids, caustic alkalis, and other hazardous chemicals at elevated temperatures, all while ensuring employee safety and environmental protection.
Our Solution
Corrosion-Resistant & High-Temperature Seals.
How it Works
The PTFE jacket of our spring-energized seals is virtually inert to all chemicals. The internal spring maintains constant sealing force, even under thermal cycling and system wear.
FFKM offers the ultimate resistance for the most severe conditions.
The Benefit
Elimination of dangerous leaks, protection of expensive process equipment, and safe operation in the most corrosive environments.
5. Aerospace & Aviation
The Challenge
Demanding performance across a vast temperature range (-65°F to 400°F+), compatibility with aerospace fuels and lubricants (e.g., Skydrol), and extreme reliability with minimal weight.
Our Solution
Precision High-Performance Seals.
How it Works
Our seals are engineered from advanced materials like filled PTFE and high-grade FKM to handle thermal shock, aggressive fluids, and the rigorous demands of flight control actuators, landing gear, and engine systems.
The Benefit
Uncompromising safety, reliability in extreme conditions, and weight reduction for critical aerospace applications.
