Product Category : Dowty Seals / Bonded Washers

The BS/A bonded seals（automatic core－positioning）are applicable to threaded pipe fittings and plug sealing in Metric System,the Britain System and BSP.The location processing of sealing groove is not specially required,so it is ideal fittings for fast and automatic installation.Its service temperature is-30℃～100℃,working pressure less than 39.2MPa...

Hydraulic cylinders operate in a variety of applications and environmental conditions. To prevent contaminates from entering the cylinder assembly and hydraulic system, Rod wiper seals,scrapers and dust seals are fitted on the external side of the cylinder head.

Wiper seals maintain sealing contact to the piston rod when the equipment is..

Rod Wiper seals maintain sealing contact to the piston rod when the equipment is stationary and in use. Without a wiper seal, the retracting piston rod could transport contaminates into the cylinder which can adversely affect performance and service life of hydraulic systems.

Hydraulic cylinders operate in a variety of applications..

Rod seals are typically single-acting seals, which means fluid pressure acts from inside the cylinder on one side of the seal only. The pressure acting on the rod seal increases contact forces between the rod seal and cylinder surfaces. Therefore, rod seal materials should be wear resistant and the rod..

The purpose of a Rod Buffer seal is to protect the rod seals by reducing pressure spikes. These pressure peaks can be far in excess of the system operating pressure. Buffer seals in combination with rod seals provide an effective rod sealing system for cylinders in heavy duty applications at..

Back-up rings (anti-extrusion rings) help prevent extrusion in high pressure applications by closing the clearance gap and reducing friction by trapping lubricant in the area of the seal. Double acting applications (using bi-directional pressure) require the use of two back-up rings, one on either side of the seal.
In single acting..

The Symmetrical U-Cup provides excellent sealing performance and very long operating life in both rod and piston applications. It has superior sealing performance and longer operating life, and is great for those tough applications with high pressures or temperatures where other seals fail.

No adhesion effect on sliding surface
Superior performance over..

Piston seal maintain sealing contact in sliding motion between the piston and cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5,800 psi). The pressure acting on the piston seal increases contact forces between the piston and..

Double-acting piston seals have a symmetrical profile (cross section) and identical sealing functions in both directions. Typically, double-acting piston seals consist of a slide ring and an energizer. The deformation of the elastomeric energizer when installed provides adequate force to keep the slide ring in dynamic sealing contact with the..

Back-up washers or Anti-extrusion rings are designed to protect o’rings and help prevent extrusion in high pressure applications by closing the clearance gap. Double acting applications (using bi-directional pressure) require the use of two back-up rings, one on either side of the o’ring.
In single acting applications (single sided pressure) where..

Cylinder Piston Rings are most frequently used today in sealing medium and high pressures for hydraulic equipment such as machine tools of all types, road and mobile machinery of all types, Heavy Duty presses,engines etc. These piston Rings for hydraulic applications are made from alloys of bronze and cast iron,..

Wear rings and guide strips accommodate radial loads of forces acting on the cylinder assembly and guide the rod in the cylinder head as well as guide the piston in the cylinder bore.

Guides are generally made of a polymer material which avoids metal-to-metal contact between moving parts in a working..

Chevron vee packings are heavy duty multi-piece single acting seals. Consisting of top and bottom adaptors (male and female adaptors) book-ending pressure rings (vee rings) in the middle to make a vee set (stack).

When installed, mechanical pressure is applied upon the adaptors which squeeze together down upon the vee rings..

A Retaining Rings is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed in a groove. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. Circlips are a type of retaining ring.

Self-locking retaining rings may be installed in..

Piston T-Seals
Designed to fit imperial o’ring housings , T-seals are an ideal replacement for o’rings. The T-shaped sealing element serves as a slide ring that’s highly resistant twisting and spiral failure. Piston T-seals seal statically against the groove ID and are suitable for pressures up to 345 bar (5,000 psi).
Piston..
