Excessive leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues. Hallite offers a wide range of piston seals that provide the ultimate in leakage control.

Single Acting Piston Seals Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.

Compare Quotations and seal the deal. Piston seals, both single- and double-acting, can be designed for and used with integrated or separate back-up rings and guide rings.

Double Acting Piston Seals Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.

Rod Seals The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. The T, which is a woven fabric reinforced polyester resin bearing is available in three forms, cut rings, spiral lengths and flat coils, and is compatible with a wide range of fluids, and is used extensively in mining applications. Tell us what you need by filling in the form.

Please enter your name. Hallite offers a wide range of hydraulic rod seals for both single-acting and double-acting systems.

The piton sealing capacity of a double-acting cylinder, capable of sealing dynamic pressure from both sides bidirectionalis achieved by choosing a double-acting seal. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration.


The choice of piston seal is decided by the way in which the cylinder operates. Please enter full name.

The steel piston has a non-metallic bearing material moulded over the outer diameter using a special proprietary process. Our T63 polyacetal wear ring is suitable for both fluid and pneumatic cylinder ssals, the T87bronze filled PTFE bearing is suitable for higher temperature applications.

It is then finish machined to provide a tight tolerance with pistpn bore of the tube and also for the installation of the chosen seal. Produced today in a wide range of sizes, bearing and seal materials, Hallite’s exclusive Unitized Piston is available off the shelf in numerous standard metric and inch sizes.

Double Acting Piston Seals. If a less aggressive rod ;iston is paired with an aggressive wiper, the wiper can scrape off the microscopically thin film of oil that remains on the rod in microscopic surface imperfections during the return stroke, resulting in system leakage.

Particular attention should be paid to pair the rod seal and the wiper for the best sealing performance. Wipers Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. Hallite offer bearings in various types of materials all of which offer high wear-resistance hallute demonstrate excellent friction ;iston.

Ram Seal for concrete pump. Vee Packing Service Vee pack sets are multiple-lip chevron seals, usually composed of a male and female adaptor and a group of three or five vee rings, are popular for sealing rods and pistons in medium to heavy duty applications and are compatible with both single and double acting cylinders. We are here to help! An accepted solution for Construction, Off Highway and Agricultural cylinders, sels Unitized Piston provides the OEM customer with proven extended service life whilst significantly reducing manufacturing and assembly costs.


Small amounts of leakage on the rod are cosmetically unattractive, and in many applications are becoming increasingly unacceptable.

Originally designed and patented by Hallite Seals over 25 years ago, the Unitized Piston continues to establish and develop itself as a unique solution for our customers many and varied applications. Company Factsheet Hallire of Business Retailer. Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.

Hallite – Double Acting Piston Seals

For a cylinder which is exclusively single-acting, capable of sealing dynamic pressure from one side unidirectionalit is always best to choose the type of gallite designed to provide optimum sealing qualities for single-acting functions. Please enter Mobile Number.

A pistkn filled nylon wear ring T offers high bearing load capacity over a broad range of temperatures, whilst our high strength nylon bearing T is suitable for telescopic applications. Save time and let us provide you with verified contacts. The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function. Please enter your Email ID. The reason is that a very high pressure can be trapped between the seals.

At the same time, it prevents any metal-to-metal contact, which will damage seaals score the surfaces and eventually cause seal damage, leakage and component damage.

Hallite Double Acting Piston Seals

Bearings The function of the Bearing or wear ring is to guide the piston and piston rod of a hydraulic cylinder, as well as to withstand arising side loads. Unitized Pistons The Hallite Type is a ready to fit complete piston.

A piston design where two single-acting seals on the piston for a double-acting cylinder are used can easily give rise to a breakdown. Mobile Number Please enter Mobile Number. Universal Products Seals Private Limited. Swivel Seals Swivel seals are designed for slow rotary applications, such as the hydraulic swivels, which allow the transmission of pressurised services between the chassis and body of mobile hydraulic equipment.
