Spring energized seals

Products

The wiper seal of DSH can be made of hard nitrile rubber and is ideal for installation in grooves to prevent dust from passing through the outside of the wiper and reducing pumping. Its outer diameter is an interference fit with the housing, which helps prevent contaminants from entering the groove. It can be effectively used in light and medium applications.

The wiper seal is equipped with a lip for removing dirt, dust or moisture that is slightly adhered to the rod. The proper proportion of our wiper lip ensures that it remains in perfect contact with the surface of the rod so as to remove deposits such as mud and ice.

It can also be made of polyester-based materials with strong wear resistance and can be greatly used in harsh environments in the mining or earthmoving industry.

The entire seal can be used with a split housing, most of which can be mounted in a blind housing. It’s unique because its protective debris completely covers the gland shell, preventing water or mud traps that are commonly seen in traditional wipers. DSH seals promises that our wiper seal provides excellent additional protection to the integrity of the hydraulic system by reducing corrosion and preventing contaminants from entering the wiper housing recess and cylinder gland, which will extend the life of systems.

PTA-Custom Elgiloy Helical Spring Energized PTFE Seal

PTA Spring Energized Seals are comprised of a wound ribbon metal spring installed in a polymer jacket. This helical shape spring affords a relatively high load versus deflection range resulting in a sealed product that can provide very tight sealing. As a highly loaded product, PTA Spring Seals should be considered when dynamics are very […]

PTB-Custom Spring Energized PTFE Seal

PTB Spring Energized PTFE Seals make use of a V-shaped spring embedded in a polymer jacket. At installation, the V shape of the spring is compressed, providing sealing energy to the seal jacket ensuring a positive seal. With a linear load curve and excellent deflection range, PTB Spring Energized PTFE Seals are a very versatile […]

PTC-Internal Face Spring Energized PTFE seal

PTC uses both flexible and rigid elements that maintain contact at a sealing interface and slide on each other. This allows a rotating element to pass through a sealed case. The elements are both mechanically and hydraulically loaded with a spring or other device to maintain contact. Internal face seals are used for static, slow-rotating […]

PTD-External Face Spring Energized PTFE seal

PTD is commonly used in static sealing applications. External face seals are typically used to remove environmental media from exposed joints, hinge points or fittings. PTFE face seals are superior to traditional O-rings in pressure management, chemical compatibility, and operating temperature range. It is very common to use in cell applications. External face seals are […]

PTU-Custom Carbon Fiber Spring Energized PTFE Seal

The PTU spring energized PTFE Seal rod & piston is not specifically designed for just one industry or application. The chemical and physical properties of its compounds make it a powerful problem solver in many situations. The seals always seem to gravitate toward certain difficult applications which include: Harsh chemicals and solvents. High temperatures up […]

PTUF-Custom Spring Energized PTFE Seal

PTUF spring energized PTFE seal, Flanged profiles are clamped axially in the gland to ensure that the seal does not spin with the shaft, especially in applications with frequent thermal cycling. Flanged seals are a special class of radial seals with an added feature to help retain the seal under rotary forces. The flange is […]

PTW-Custom Spring Energized PTFE Seal

DSH Seals designs and manufactures PTFE and other high-performance polymer composite spring-energized seals in inch and metric sizes for linear or reciprocating rod and piston sealing applications, for rotating shafts and bores, and for static and axial face sealing applications of low and high viscous liquids and gaseous media under low and high pressure. ◆◆The […]
