Cylinder Seal Kit Component Solutions by Polypac
Reliable Components for Critical Hydraulic Applications
Polypac's Cylinder Seal Kit Component line provides engineered sealing parts designed to withstand high pressure, temperature swings, and abrasive environments. Our kits integrate High Quality O-rings, PTFE-based guide rings, and dynamic seals to optimize cylinder life and reduce leakage risk — ideal for construction, mobile hydraulics, and industrial presses.
Advanced Materials and Manufacturing
We manufacture Cylinder Seal Kit Component parts using a broad range of materials, from filled PTFE (bronze, carbon, graphite, MoS₂, glass) to elastomers such as NBR, FKM, silicone, EPDM, and FFKM. Our 10,000+ m² facility and 8,000 m² production space house industry-leading molding and machining equipment, ensuring consistent tolerances and repeatable performance across high-volume production runs.
Custom Sealing Solutions for Special Conditions
When standard kits won’t do, Polypac customizes Cylinder Seal Kit Component assemblies to meet unique media, temperature, or abrasion challenges. We collaborate with universities and research institutes to develop bespoke compounds and geometries, delivering solutions for hydraulic fluids, aggressive chemicals, and extreme duty cycles.
Rigorous Testing and Quality Assurance
Every Cylinder Seal Kit Component undergoes stringent testing: dimensional inspection, material validation, and performance checks under simulated operating conditions. Our in-house labs and advanced testing rigs validate wear resistance, compression set, and sealing integrity so you can trust field performance.

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.
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.
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.
