Product Description

Polypac Low-Profile Seal Design — Overview

Polypac Low-Profile Seals are engineered for applications where space is limited but sealing reliability cannot be compromised. Designed for hydraulic cylinders, rotary shafts, and compact actuators, these seals deliver strong leak prevention, low friction, and long service life.

Why choose low-profile seals?

Low-profile seals reduce radial height and installation space while maintaining excellent sealing performance. They are ideal for modern, compact machines and equipment that demand high reliability under pressure, temperature swings, and aggressive fluids.

Key Features and Benefits

  • Compact design: Saves space and simplifies assembly in tight housings.
  • Low friction: Reduces wear and energy loss for smoother motion.
  • Durable materials: Available in NBR, FKM, EPDM, silicone, FFKM and filled PTFE varieties for wide chemical and temperature resistance.
  • Customizable: Tailored profiles and compound choices to match your operating conditions.
  • Reliable sealing: Prevents leaks under high pressure and dynamic movement.

Materials and Compatibility

Polypac leverages decades of material expertise — from bronze-, carbon- and MoS₂-filled PTFE to modern elastomers such as FKM and FFKM — to recommend the best compound for your fluid, temperature, and wear requirements.

Quality, Testing and Custom Service

Founded in 2008, Polypac operates a 10,000+ m² facility with 8,000 m² of factory space and advanced production and testing equipment. We work closely with universities and research institutions to ensure materials and designs meet strict performance standards. Custom prototypes, small-batch runs and full-scale production are supported with thorough testing and QC.

Typical Applications

Hydraulic systems, mobile machinery, automotive actuators, industrial robots, oil & gas equipment, and any application where compact, durable sealing is required.

FAQ

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 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.
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.
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.
