NBR FKM Rubber Seal Hydraulic Piston Rod Seal

SPGO hole square ring, also known as SPGO ring, is a bidirectional piston outer diameter seal ring, it and an O-ring installed together, with a generation of friction resistance, no crawling, wear resistance, long service life, etc. Dynamic and static sealing effect.

Material: PTFE+ bronze NBR/FKM

Working speed: 15 m/s

Operating temperature: -30 ~ +120ºC (NBR) -30 ~ +200ºC (fluorine glue)

Working pressure: ≤40MPa

Medium: Suitable for petroleum-based hydraulic oil and environmentally safe hydraulic oil.

Advantages: Lattice ring is a double acting sealing ring, with low friction resistance, no crawling phenomenon, static and static sealing effect is very good.

Groove structure is simple, high temperature resistance, high adaptability to working conditions.

Chemical Properties:

Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.

Non-flammability: Oxygen limit index below 90.

Acid and alkaline resistance: insoluble in strong acids, strong bases and organic solvents (including magic acid, namely fluoroantimony sulfonic acid).

Oxidation resistance: Resistance to corrosion by strong oxidants.

Acid base: neutral.

The GSF Glace ring consists of an anti-wear filled PTFE ring and rubber O-ring, which can withstand high pressure, low pressure or alternating pressure two-way reciprocating sealing ring. Suitable for hydraulic cylinder piston seal. Generally used with guide ring.

Note: Split grooves should be used for specifications with aperture less than 40.

Temperature: ≤120ºC (NBR)

200 ºC or less (FKM)

Pressure: ≤40Mpa

Speed: ≤5m/s

Medium: petroleum based hydraulic oil, refractory emulsion, environmental protection and safety hydraulic fluid, biological oil, water material

The material

O-ring: NBR or FKM;

Anti-wear ring: filled with tetrafluoroPTFE PTFE-bronze, or PTFE-carbon
