Polypac Flexible Low Temperature Seals

Overview

Polypac Flexible Low Temperature Seals are engineered to maintain elasticity and sealing integrity in very low-temperature environments. Designed for demanding hydraulic, automotive, cryogenic and outdoor systems, these seals combine proven materials and precise manufacturing to reduce leakage, improve service life, and withstand extreme cold.

Key Features

• Consistent flexibility at low temperatures — formulated elastomers retain resilience where ordinary seals harden.
• Wide material options — including specially compounded silicones, low-temperature rubbers and PTFE-based composites to suit different operating conditions.
• Custom sizes and profiles — produced to tight tolerances for O-rings, rubber rings and custom seal shapes.
• High-quality manufacturing — advanced production and testing equipment ensure repeatable performance and reliability.

Applications

These seals are ideal for systems exposed to cold or fluctuating temperatures, such as:

• Cryogenic equipment and low-temperature processing
• Cold-climate automotive and HVAC systems
• Outdoor hydraulic and pneumatic assemblies
• Food processing, medical devices and instrumentation requiring low-temp resilience
