Piston Service Kits for 2H Series Tie Rod Hydraulic Cylinders

Our piston service kits are OEM-matched repair spare parts exclusively engineered for Parker 2H series tie rod cylinders, covering all standard cylinder bore sizes from 1½” to 12″. Three distinct piston seal configurations are offered to match different load, pressure and working cycle requirements.

1. PRxxxx Cast Iron Ring Piston Kits

These kits contain full sealing components for cast iron ring style pistons. The cast iron wear rings deliver superior wear resistance and smooth reciprocating movement, paired with standard O-ring sealing elements. Ideal for medium-duty, continuous cycle industrial applications with stable operating pressure.

2. PKxxxxHLL Lipseal Piston Kits

Designed for standard lipseal integrated pistons, each pack includes a single-piece bidirectional polyurethane lip seal and guide wear strips. This all-in-one seal design simplifies on-site assembly, balances sealing performance and procurement cost, making it the universal choice for regular light & medium load maintenance.

3. PKxxxxHK Hi-Load Piston Kits

Heavy-duty high-load piston repair kits equipped with reinforced lip seals and anti-extrusion backup rings. Optimized to withstand high system pressure, impact loads and lateral piston side forces. Perfect for heavy machinery, hydraulic presses and harsh working conditions where extended seal lifespan is critical.

Q: What’s the MOQ of customized tie-rod cylinder?

A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.

Q:What’s the lead time of customized tie-rod cylinder?

A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.

Q: Are you the manufacturer of hydrualic cylinder?

A: Sure, we are the manufacutuer and trading of hydraulic cylinder.

Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?

A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through

a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.

Q: I have a drawing, could you customized cylinder as my drawing?

A: Sure. Show us the drawing, we will quote for you soonest.

Q: Could you make the cylinder which is not on the above data sheet?

A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.
