Hydraulic & Pneumatic

In Hydraulic Industry, the choice of material for the best sealing solution is determined by thermochemical and environmental conditions, the groove, special characteristics and sometimes the sheer scale of machines.

This is especially true for unbalanced mechanical seal combinations in steel mills to large-diameter split elastomer seals in industrial fans.

We are your partner for the development and production of High-quality hydraulic seals/o-rings with customized designs.

Whether it's hydropower, presses, cranes, the metal industry, the maritime sector, conveyor technology or hydraulic steel structures – wherever the requirements for service life, corrosion resistance, installation space, weight optimisation or temperature are particularly high, we supply you with tailor-made hydraulic seals/o-rings parts and hydraulic rotary joints of the highest quality, from individual items to series production.

Large dimensions result in large tolerances and gaps that when combined with pressure or force can cause high stresses in the seal. The sheer scale of equipment often requires designs that allow for on-site maintenance, with only partial disassembly, but also fabricated from a variety of materials better suited to such dimensions.

Customized designs are needed to meet the demands of Hydraulic industry. Hao Seal Tech basic range consists of seals/o-rings, along with bespoke mechanical Seals /O-rings.
