Guide Ring for Hydraulic Seals - Polypac Precision Guide Rings
Guide Ring for Hydraulic Seals: Reliable Guidance, Reduced Wear
Polypac's guide ring for hydraulic seals provides durable axial and radial guidance to prevent seal extrusion, eliminate metal-to-metal contact, and extend seal life. Engineered for hydraulic cylinders, pistons, and rods operating under high pressure, our guide rings ensure precise alignment while minimizing friction and wear across a wide range of temperatures and media.
Materials & Compatibility
Choose from engineered polymers, filled PTFE variants, and custom elastomer-backed designs to match your application. With roots in filled PTFE (bronze, carbon, graphite, MoS₂, glass) and extended offerings like NBR, FKM, EPDM, silicone, and FFKM O-rings, Polypac delivers guide ring for hydraulic seals compatible with aggressive fluids, extreme temperatures, and abrasive environments.
Performance Benefits
Our guide rings reduce friction, prevent extrusion, and stabilize sealing elements to improve cycle life and system efficiency. By guiding the seal precisely, they reduce lateral load, reduce leakage risk, and lower maintenance downtime—translating to measurable savings for OEMs and maintenance teams.

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.
What is the difference between NBR and FKM materials?
NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F). FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.
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.
What is the difference between a static seal and a dynamic seal?
A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
