    Rod Gland Seal Kits for Parker Series HD Hydraulic Cylinders

    Product Overview

    Rod Gland Seal Kits (coded as RG Series) are genuine OEM cartridge repair assemblies exclusively engineered for Parker HD heavy-duty tie rod hydraulic cylinders (including legacy HDC units). These complete gland service kits integrate the bronze gland housing and all matching rod sealing components, enabling one-step overhaul of the rod gland assembly without separate part sourcing.
    HD series cylinders are mill-type heavy-duty actuators widely deployed in steel mills, mining, injection molding, construction machinery and high-pressure hydraulic circuits. The RG gland kits replace outdated multi-lip packing (pre‑1987 HD cylinders) and fit all post‑1987 HD models with standard single-lip rod seal configuration (Seal Symbol #41).
    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.

    • All-in-One Cartridge Design

      Complete matched gland and sealing set eliminates mismatched spare parts, cuts maintenance downtime and avoids leakage risks caused by incompatible seals.

    • Heavy-Duty Mill-Type Durability

      Bronze bearing + wear-resistant PU primary seal withstand high-frequency reciprocation, iron dust contamination and impact loads from metallurgical and mining equipment.

    • Universal Compatibility

      RG gland kits fit all HD / HDC cylinder generations, covering all standard inch rod diameters from 5/8" up to 8". Separate RK rod seal-only kits (without bronze gland) are available for routine minor seal replacement when the original gland housing remains undamaged.

    • Dry Rod Sealing Performance

      Multi-lip primary seal + dual-action wiper combination delivers nearly dry rod running, drastically reducing external oil dripping and workplace fluid contamination.

    • Before fitting, thoroughly polish and deburr the piston rod surface; wrap thin shim material over rod threads to avoid cutting seal lips during gland installation.
    • Lubricate all sealing elements with matching hydraulic fluid prior to assembly.
    • Torque gland retainer screws to Parker specified values to prevent gland loosening under vibration in mill heavy-load environments.
    • Replace the full RG kit instead of single seals during overhaul to avoid uneven wear and secondary leakage failure.
