Hydraulic Seals

The mission of hydraulic seals is to prevent leakage of fluid from the cylinder. The hydraulic seals are also need to withstand the high pressure and extreme temperatures. 

GMORS supplies a range of seals for the common application within hydraulic cylinders. We develop the suitable materials which can perform a well abrasion resistance.

Double Lip Rod Wiper
This seal prevents entry of dust, and protects equipment by maintaining sealing performance of the packing. It can be fitted into an integrated groove. It's a double-lip all rubber wiper seal that prevents oil scraping off.
Material : NBR/FKM
Working Temperature: -35°C~+80°C/-10°C~+150°C
Surface Speed : ≦1.0m/s

TPU Double Lip Rod Wiper
This seal prevents entry of dust, and protects equipment by maintaining sealing performance of the packing. It can be fitted into an integrated groove. It's a double-lip all rubber wiper seal that prevents oil scraping off.

Material : ESTER TPU
Working Temperature: -30°C~+80°C
Surface Speed : ≦1.0m/s

Packing for Piston
Special one ring shaped packing for both sides pressure with seal lip. With the same sealing performance as U-packing. Possible to make a piston compact. PWL-Bearings for bearings combined with back-up rings are being prepared.

Material : NBR/FKM
Working Pressure: ≦14 Mpa
Working Temperature: -35°C~+80°C/-10°C~+150°C
Surface Speed : ≦1.0m/s

UF1

Symmetrical Piston/ Rod U-Cup Seal
This can be used for both piston and rod seals, and has a small section that can be fitted into an integrated groove.

Material : NBR/FKM
Working Pressure: ≦14 Mpa
Working Temperature: -35°C~+80°C/-10°C~+150°C
Surface Speed : ≦1.0m/s

UF2

TPU Symmetrical Piston/ Rod U-Cup Seal
This can be used for both piston and rod seals. It has a large section and can be used for a wide range of operations, with excellent wear resistance and sealing ability.

Material : ESTER TPU
Working Pressure: ≦35 MPA
Working Temperature: -30°C~+80°C
Surface Speed: ≦0.8m/s

UF4

TPU Symmetrical Piston/Rod U-Cup Seal
Used for both piston and rod seals, this packing has a small section and can be fitted in an integrated groove. Improved design prevents damages caused by back pressure.

Material : ESTER TPU
Working Pressure: ≦21 Mpa
Working Temperature: -30°C~+80°C
Surface Speed: ≦0.8m/s

UH1

Symmetrical Piston/Rod U-Cup Seal
The O-Ring energized lips assure a uniform, positive lip contact plus excellent low pressure sealing. Seal depth is equal to radial width. UH1 is used to interchange an existing hydraulic packing and/or O-Rings.

Material : ESTER TPU
Working Pressure: ≦35 Mpa
Working Temperature: -30°C~+80°C
Surface Speed: ≦0.8m/s

UH2

Symmetrical Piston/ Rod U-Cup Seal
The back beveled sealing lip provides greater film breaking and increased until loading at the sealing surface. Seal depth is generally 1.5 times the cross section of radial width to insure seal stability in most rugged applications. ROD SEAL use is preferred.

Material : ESTER TPU
Working Pressure: ≦35 Mpa
Working Temperature: -30°C~+80°C
Surface Speed: ≦0.8m/s
