Polypac Mining Cylinder Seal Solutions
Polypac Mining Cylinder Seal Solutions
Product Overview
Polypac designs and manufactures High Quality Mining Cylinder Seal products engineered for the extreme demands of mining hydraulics. Our seals protect cylinders, rods and pistons against abrasion, contamination and severe pressures. With experience dating to 2008, Polypac combines proven filled PTFE formulations and elastomeric O-rings to deliver long service life and minimal downtime.
Materials & Performance
We offer bronze-filled PTFE, carbon-filled PTFE, graphite PTFE, MoS₂-filled PTFE and glass-filled PTFE, plus elastomers such as NBR, FKM, silicone, EPDM and FFKM. Each Mining Cylinder Seal is selected for optimal friction, wear resistance and chemical compatibility, helping maintain seal integrity under high load, temperature swings and contaminated oil common in mining operations.
Custom Manufacturing & R&D
Polypac’s 10,000+ m² facility and advanced production equipment support bespoke seal geometries and material blends tailored to special working conditions. We partner with universities and research institutes to refine sealing compounds and to develop solutions that overcome unique mining challenges—minimized leakage, extended maintenance intervals and improved system efficiency.
Quality Control & Testing
Strict process control and comprehensive testing ensure every Mining Cylinder Seal meets performance targets. Our in-house test rigs simulate real-world hydraulic cycles, pressure spikes and contaminant exposure so you receive reliable, validated components backed by measurable data.
Applications & Benefits
Polypac seals are optimized for excavators, haul trucks, drills, loaders and hydraulic presses used in mining. Benefits include reduced wear, better oil retention, lower friction and predictable lifetime — all contributing to reduced total cost of ownership and higher operational uptime.
Ordering & Support
Whether you need standard sizes or fully customized Mining Cylinder Seal solutions, Polypac provides expert material selection, rapid prototyping and scalable production. Contact our team for application review, sample evaluation and tailored sealing strategies that keep your equipment working harder, longer.

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.
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.
Why did my O-ring fail prematurely?
Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.
How can I prevent seal damage during installation?
Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.
