The MA43 profile belongs to the family of rod seals, fitted in the cylinder head to keep the fluid in along the chromed rod. An internal stainless-steel spring keeps the sealing force constant even at extreme temperatures. For the same housing sizes it can replace equivalent profiles such as SNI43, RS-87, K701, NLI, FOI.

Materials and operating conditions

  • Materials: PTFE + carbon, PTFE and PTFE + bronze
  • Temperature: -150 °C to +250 °C
  • Maximum pressure: 350 bar
  • Maximum speed: 15 m/s
  • Catalogue sizes: 91 (inner diameter from 5 to 1,060 mm)

Indicative values: actual limits depend on the fluid, surface finish and fitting tolerances.

Where it is used

They are used in the hydraulic cylinders of earth-moving machines, tractors and farm machinery, cranes, presses, forklifts and industrial plant: wherever a chromed rod moves in and out of a pressurised cylinder.

How to choose MA43

  • Check the housing sizes: rod diameter, groove diameter and width.
  • Consider the cylinder's maximum pressure, speed and working temperature.
  • Filled PTFE (bronze, glass or carbon): minimal friction and no stick-slip, suitable for high speeds.

Measure the rod diameter (d), the groove diameter in the head (D) and the groove width (H), then enter the values in the table filters.

Frequently asked questions

Which materials is MA43 available in?

MA43 is available in PTFE + carbon, PTFE and PTFE + bronze. The stated working temperature ranges from -150 °C to +250 °C.

What is the maximum pressure for MA43?

According to the technical data, MA43 works up to 350 bar at speeds up to 15 m/s. The real limit depends on fluid, temperature and extrusion gap.

Which profiles is MA43 interchangeable with?

MA43 is interchangeable with SNI43, RS-87, K701, NLI, FOI for the same housing sizes. If in doubt, check the dimensions or contact us.
