Polypac Guide Ring — Durable Hydraulic Guide Rings for Precision Sealing

Product Overview

Polypac Guide Rings are engineered to guide piston and rod movement in hydraulic cylinders while protecting seals and preventing metal-to-metal contact. Designed for durability and consistent performance, our guide rings reduce friction, extend seal life, and improve overall system reliability.

What is a Guide Ring?

A guide ring is a non-elastic component placed between the piston/rod and the cylinder to provide radial guidance, absorb side loads, and protect soft sealing elements. Unlike O-rings, guide rings do not seal fluid but keep components aligned to prevent uneven wear.

Key Benefits

• Wear resistance: Engineered materials minimize abrasion and extend service intervals.
• Low friction: Smooth operation reduces power loss and heat build-up.
• Seal protection: Prevents damage to adjacent rubber or PTFE seals.
• Stable guidance: Improves accuracy and reduces vibration in hydraulic systems.
• Customizable: Available in sizes and materials matched to your application.

Materials & Customization

Polypac offers guide rings in a range of materials, including filled PTFE variants (bronze, carbon, graphite, MoS₂, glass) and engineered polymers. We also supply complementary O-rings in NBR, FKM, silicone, EPDM, and FFKM for full sealing solutions. Our factory supports custom profiles and material blends for special working conditions like high temperature, corrosive fluids, or heavy side loads.
