150N4040 Sauer Danfoss Seal Kit
This is an original 150N4040 Sauer Danfoss Seal Kit and can service all OSPB, OSPC, and OSPF series Sauer Danfoss steering valves regardless of when they were made.
The 150N4040 Sauer Danfoss Seal Kit services all OSPB, OSPC, OSPF, and OSPQ series Sauer Danfoss steering valves.
This is an original 150N4040 Sauer Danfoss seal kit and includes two different sets of O-rings and two input shaft seals to cover the range of possibilities due to manufacturing changes that Danfoss has made over the years. Although there is a also a 3rd input shaft seal variation using a lip seal that has been used over the years and is in Danfoss seal kit 150-4267, this can be replaced with the kin ring/oring combination included in this kit in the red plastic protectors shown. If you have other than an OSPB , OSPC, OSPF, or OSPQ model identifier prefix then please call for assistance in determining the correct seal kit.
