Sealing Sleeve 15mm

The 15x24x7 oil seal is a sealing element used in drive assemblies of pressure washers, where tightness in the oil zone must be maintained while working with a shaft or axle. In service practice, it is replaced during oil-leak repairs, gearbox regeneration, and overhauls of the machine’s mechanical parts.

MPN / reference: 42907
Size: 15x24x7

APPLICATION

The oil seal is used in typical service work:

• sealing an axle or shaft in the oil section of an assembly,
• repairing oil leaks in the drive and gearbox,
• rebuilding mechanical parts of the pressure washer during overhaul,
• inspections of machines used intensively in workshops, service environments, and industrial applications.

SYMPTOMS - WHEN REPLACEMENT IS RECOMMENDED

Replacement is indicated when the following appear:

• oil leaks around the shaft, axle, or drive housing,
• traces of oil “sweating” at the seal,
• reduced tightness after operation under load,
• a hardened, cracked, or deformed sealing lip after disassembly,
• signs of wear on the surface cooperating with the seal.

HOW TO CHOOSE THE RIGHT PART

Selection of the oil seal should be done carefully:

• verify the 15x24x7 size,
• confirm the manufacturer number: MPN 42907,
• compare with the removed part: inner diameter, outer diameter, height, and working profile.

With oil seals, even a small dimensional difference may result in leakage or rapid wear of the sealing lip.

COMPATIBILITY

The oil seal should be selected based on MPN 42907 and the 15x24x7 size, according to the parts list for the specific assembly. Selection should not be based solely on a similar size without verification in the machine’s service documentation.

[faq]

Does the 7 mm height matter when selecting an oil seal?|Yes. Besides the inner and outer diameter, height also matters because it affects seating in the housing and proper loading of the working lip.

Will a new oil seal solve the problem if the shaft is already worn?|Not always. If the shaft surface has grooves, pitting, or excessive wear, the new seal may start leaking quickly. That is why it is worth inspecting the cooperating part during service.

Which installation mistakes most often cause quick seal damage?|Most commonly: installation on a dirty surface, misalignment in the housing, damaging the lip during installation, and failure to check the shaft condition and installation edges.

Does an oil leak always mean a damaged oil seal?|No. The leak can also come from other seals, housing joints, or cracks in the casing. The oil seal becomes the main suspect especially when the oil trace repeatedly returns around the axle/shaft area.

Can I select a replacement only by the 15x24x7 size?|Technically it is a starting point, but the safest way is to confirm compatibility by MPN 42907 and by comparing with the removed part, because the working profile and application point are very important.
