Cylinder Body Seal Kits for Parker HD Series Hydraulic Cylinders
Product Overview
Cylinder Body Seal Kits (CB kits) are genuine OEM complete static sealing repair packages specially developed for Parker HD heavy-duty tie rod hydraulic cylinders, including all standard and legacy HDC models.
These kits serve the static sealing joints between cylinder barrel, front end head and rear end cap, which are critical for sealing the cylinder main body. Distinct from dynamic repair kits such as piston seal kits and rod gland seal kits, CB kits focus solely on stationary mating surfaces without reciprocating friction. Designed for mill-type heavy-duty working conditions, they withstand continuous high pressure, frequent pressure shocks and harsh polluted environments in metallurgy, mining and heavy machinery.
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
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.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
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.
A: Sure. Show us the drawing, we will quote for you soonest.
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.

- Compatible media: Synthetic ester hydraulic oil, phosphate ester fire-resistant fluid and high-temperature thermal oil
- Application: Hot rolling mills, high-temperature hydraulic circuits and equipment exposed to chemically aggressive fluids
- Prevent external leakage at cylinder body joints
The O-rings tightly seal the gaps between the cylinder barrel and two end caps to stop oil seepage under sustained high pressure, avoiding fluid waste and workshop contamination.
- Stabilize internal system pressure
Sound static sealing maintains a fully enclosed pressure chamber inside the cylinder. Failed body seals will cause pressure drop, insufficient cylinder thrust and unstable clamping performance.
- Protect seals from extrusion damage
Backup rings block O-rings from being squeezed into assembly clearances under peak pressure and impact loads, extending the service life of static sealing elements.
- Block external contaminants
Intact body sealing prevents cooling water, metal dust and mill scale from penetrating into the cylinder barrel, reducing abrasion damage to internal piston seals and sliding surfaces.
