This section covers hydraulic sealing: O-rings, rod seals, wiper seals, piston seals, back-up rings, guide rings, flat seals, copper and aluminium washers, quad rings and complete seal kits. All seals are supplied as genuine parts; material and hardness follow the original manufacturer standard. A seal is matched by the groove dimensions and the original profile code, not only by the rod or bore diameter, so the old part number or a photo of the cross-section is the fastest way to identify it. Complete kits contain every seal needed to reseal one cylinder head or valve. Send the machine model, cylinder part number or a photo of the old seal and we reply within 24 hours with the exact part.

Frequently Asked Questions

Do you supply genuine parts or Chinese equivalents?

Genuine parts are our main business. If you need a lower-cost option, we can also look for a Chinese-made equivalent with the same mounting dimensions and ratings.

What is the lead time?

It depends on the supplier. If the factory has stock or produces in China, we ship quickly. A factory order that must be manufactured or shipped from abroad takes longer. We confirm the exact date in your quote.

How do I place an order?

Send the part number, a photo of the nameplate, or the machine model. We confirm availability and price within 24 hours.

What are the payment and shipping terms?

EXW by default. 20-50% prepayment, balance before shipment. We can work with your freight forwarder.

What sealing products do you supply?

O-rings, rod seals, wiper seals, piston seals, back-up rings, guide rings, flat seals and seal kits.

Are the seals genuine?

Yes, all seals are genuine parts. Material and hardness follow the original manufacturer standard.
