Sealing elements | Parker Sealing & Shielding, Parker O-Ring
Sealing products ranging from standard O-rings and extruded silicone profiles, custom molded shapes, to highly complex composite seals and metal seals for extreme application environments.
Sealing elements are used to protect sensitive electronic equipment from the harmful effects of electromagnetic interference (EMI) and from thermal energy
Our sealing elements, like gaskets, are composite products that fully exploit the unique properties of elastomer, polymer, metal or ceramic materials, in enterprising and innovative combinations.
Precision seals for hydraulic systems
Hydraulic sealing systems are used in a wide range of applications, from construction machinery, which must work in the most difficult conditions of pressure, temperature and fluids, up to industrial hydraulic systems with water in pressure multipliers, who work with extreme requirements with respect to lubrication, wear and corrosion.
Sealing systems in typical applications
For mobile hydraulic systems (excavators, elevators) and for fixed hydraulic systems (industrial cylinders, machine tools and for injection molding)
Gasket compounds for fluid technology
Rubber - resistant and not resistant to mineral oil, compounds for membranes, polyurethane compounds, rubber / fabric compounds, plastic materials, compounds for O-rings for skates
Simple and double-acting wiper rings
Designed to prevent the penetration of dust, dirt, sand and metal scraps, with good wear resistance and resistance to high temperatures in the case of choosing a suitable compound.
Scraper ring with metal cage (also with double effect) for hydraulic cylinders to reduce the risk of scoring caused by contaminants from external sources trapped in the sliding parts
Slipper Seal® Raschiatore a doppio effetto
Used in the stems and pistons with axial movement to avoid the development of scratches.
The guide elements and seals are protected and the life of the sealing system is longer. The AD profile consists of a PTFE scraper ring and an elastomer O-ring as a preload element. Combines two functions: scraping against external contamination and a sealing function that reduces the film of residual oil
Guiding elements
Guide rings and bands prevent metallic contact between pistons and cylinders or rods where forces act perpendicular to the direction of movement.
Slipper Seal® Guide band (piston / rod), Guide belt (piston / rod), Guide ring (rod), Guide ring (piston), Rod seal (Slipper Seal®), Piston seal, Slipper Seal® Piston seal set .
O-ring
Made with a polyurethane compound with a very low compression deformation, more resistant to extrusion.
Thanks to their high abrasion resistance, polyurethane O-rings are also suitable for dynamic applications.
Excellent results have been obtained, for example with air valve seals on pilot pistons or on the dynamic sealing system of the main coil. Also in applications with short stroke positioning and fixing cylinders, and in valves for systems that operate with low lubrication HFA fluids. Polyurethane O-rings are used for control purposes.
Static radial seal, flange and for rotary distributors
HS profile seals as a possible alternative to the O-Ring and anti-extrusion ring conventionally used for static sealing applications at high pressures. The robust symmetric sealing geometry and the use of Parker polyurethane compounds particularly resistant to extrusion not only simplify assembly, but also improve the sealing effect under pulsating pressure conditions.
Precision seals for pneumatic systems
The pneumatic seals allow you to follow new design and technical options.
Special compounds are available for pneumatic sealing solutions, which combine the advantages of low friction, minimal wear and long life. The variety of our range of compounds offers the correct choice of material for each application requirement.
Sealing systems for pneumatic applications
Pneumatic systems (Cylinder, Short stroke cylinder, Spool valve, Pilot valve with shutter.
Gasket compounds for fluid technology
Rubber - resistant and not resistant to mineral oil, compounds for membranes, polyurethane compounds, rubber / fabric compounds, plastic materials, compounds for O-rings for skates
Rod seals
Rod seals with scraper, rod seals with scraper for anti-rotation pneumatic cylinders, with lip specially developed for use in pneumatic systems. Resistance to high temperatures in the case of the choice of a suitable mixture
Rod seal / scraper
The EU seal / scraper for pneumatic cylinder rod simultaneously performs three functions: seal, scraper, guide. Slipper Seal® Set Seal / scraper for rod, Seal / scraper and guide element.
Piston seals
Piston seals, single acting, double acting, monobloc pistons, single acting and double acting, piston seal / guide element. Slipper Seal® Composite seal for piston. Monobloc piston with integrated damper, Monobloc piston with magnetic ring and integrated damper
Scraper and damper ring, Slipper Seal® Guide band (piston)
O-Ring
Robust seal profile for the toughest operating conditions.
Thanks to their high abrasion resistance, polyurethane O-rings are also suitable for dynamic applications. Excellent results have been obtained, for example with air valve seals on pilot pistons or on the dynamic sealing system of the main coil. Also in applications with short stroke positioning and fixing cylinders, and in valves for systems that operate with low lubrication HFA fluids.
O-Ring Division
The O-Ring division designs and manufactures engineered elastomeric O-rings, including high performance materials for almost all sealing applications.
The O-rings are available in all sizes and can be molded in a wide range of elastomeric compounds ranging from basic neoprene to special perfluorinated materials.
They are recommended for both static and dynamic sealing service in practically all vacuum, gas and liquid applications.
Production capabilities / technologies
Internal elastomeric mixing and tools, computer-controlled compression and injection molding, liquid injection molding (LIM), automated visual inspection, co-injection molding
Products and accessories
