OptiSeal®
OptiSeal®
OptiSeal® is a high-performance sealing solution with a U-shaped jacket made of Armorlene® thermoplastic material. It includes a metal spring for low-pressure sealing and becomes pressure-energized as system pressure increases.

Cap Seal
Cap Seal
Cap Seal is a cost-effective solution preventing extrusion and O-ring spiral failure. It consists of a dual-acting seal with Armorlene® PTFE material cap and Arylast™ elastomeric energizer. Ensures non-stick-slip starting and superior dry running.

Piston Ring
Piston Ring
Piston Ring is a low-friction hydraulic seal with two step-cut Armorlene® rings. It eliminates the need for a wave spring and meets AS4716 groove width standards. Metal expanders enhance temperature range and chemical resistance.

OptiSeal® Face Seal
OptiSeal® Face Seal
The OptiSeal® Face Seals are used in static seal applications. They have an axial squeeze design for external or internal pressure. Increasing compression against the seal presses the jacket lips against the gland surface, ensuring stability and resistance. The beveled lip offers excellent sealability for high unit loading applications.

Static Face Seal
Static Face Seal
Static Face Seals replace O-rings in face-mounted assemblies. They feature an L-shaped Arylast™ elastomeric element and an energized back-up ring made of Armorlene® or Arylex®.

Backup Ring
Backup Ring
The rectangular Backup Ring prevents extrusion of O-rings in seal glands. Made of PTFE or similar material, it provides support and eliminates metal-to-metal contact.

Bearings
Bearings
Bearings absorb loads, reduce wear, and prevent scoring. Actuator hardware affects space. Optimal size selection considers radial cross-section and axial width. Polymeric bearings require increased clearance. Safety factors account for material compression and loading.

Scrapers
Scrapers
Scrapers have an Armorlene® PTFE Ring and O-Ring or spring energizer. They prevent contamination in hydraulic cylinders during rod retraction. Single lip scrapers block external debris, while double-acting scrapers remove fluid film and prevent leakage. OptiSeal® scrapers excel in extreme conditions.
