PISTON SEAL

DAS

Description

The Compact Seal is a double-acting seal and guide element comprising of a rubber seal, two split support rings and two split bearings, located either side of the seal. A high-performing, double acting compact piston seal composed of a profiled rubber ring, two polyurethane back-up rings and two L-shaped POM wear/back-up rings. Good sealing effect. Excellent extrusion & wear resistance. Reliable sealing for significant and sudden pressure variations. Assembly in closed groove, reduced machined cost. Economic wear and sealing solution.

Application

Mobile hydraulics Excavators Heavy duty hydraulic cylinders

Materials

Polyoxymethylene(POM) + Nitrile rubber(NBR) + Polyurethane(PU)

PISTON SEAL

FS

Description

The FS-seal is a relatively large cross section spring energized rubber casing and tubing hanger seal for wellheads that always has the springs on the internal surface. FS-seals are used against rough surface finish and wider dimensional and geometrical tolerances of casing and tubing. Sealing materials utilized for wellheads need to withstand pressures as high as 1 034 bar (15 000 psi) and temperatures of 149º C (300º F). All our FS-seals successfully passed the test according to API 6A annex F PR2 with the following parameters: * Improved equipment reliability. * Reduced installation time, delay and damage. * Protects system from loose materials.

PISTON SEAL

KZT

Description

KZT is used in combination with piston seals and anti-wear rings. This product is used in combination with anti-wear and piston ring seals to prevent cylinder oil from mixing with foreign particles, resulting in seal damage and a long service life. The piston rod seal is used in combination with a metal bushing to prevent damage to the rod due to the impurity immersion function of the PTFE. It is used to move the piston and rod in the cylinder. It has good guiding effect and can absorb radial force at any time to prevent metal-metal contact in the cylinder and reduce friction. According to your specific requirements, KZT has many materials that can be used for the guide ring.

PISTON SEAL

MHM

Description

High-performing, double acting compact piston seal composed of a profiled rubber ring, two polyurethane back-up rings and two POM back-up rings. Good sealing effect. Excellent extrusion & wear resistance. Reliable sealing for significant and sudden pressure variations. Assembly in closed groove, reduced machined costs. * High resistance to gap extrusion. * Particularly strong wear resistance. * Insensitivity to shock loads and pressure peaks.

Application

Agriculture Mobile machinery Hydraulic cylinders

Materials

Polyurethane (PU) + Nitrile Rubber (NBR)

BACK-UP RING

N4W

Description

The support ring of the hydraulic cylinder seal is installed on the inside of the end cover of the hydraulic cylinder. * To support the piston rod; preventing the piston rod from vertical pressure to bring uneven sealing pressure caused by the rod seal and the poor sealing effect. Short life and other effects. * Second, the guide ring of the hydraulic cylinder seal ring The back up ring of the hydraulic cylinder seal is installed on the piston, and its main function is to guide the piston to perform linear motion, to prevent the piston from deviating due to uneven force, causing internal leakage and reducing the life of the seal. * The service life of the back up ring and the support ring directly affects the use effect and life of the piston seal and the piston rod seal, so the requirements for the back up ring are also high, such as low friction coefficient, high hardness, long service life, etc. . * There are many forms of guide belts and support rings, and they are also used in combination with the main seal.

PISTON SEAL

OK

Description

The profile OK piston sealing set is primarily designed for heavy-duty hydraulic applications and is preferably used in double-acting cylinders. It is extremely robust and withstands even extreme pressure peaks.The sealing set consists of a plastic slide ring and an elastomer energizer. * Extreme wear resistance. * Easy installation on single-part piston without assembly aids due to the split design of the sealing ring. * Assembly on one-part piston is possible. * Insensitive to extreme pressure peaks. * Extremely high extrusion resistance. * High extrusion resistance in case of high pressures and large gaps due to the special compound properties of the seal ring. * Dimensions according to ISO ­7425-1. * Short axial assembly length. * Installation in closed and undercut housings. * Further dimensions of machined series with short lead times available.

Application

Heavy-duty hydraulic applications.
