Sealing Sleeve 15mm

The 15 mm hard seal / cup seal (hard ring) with dimensions 15×24×5/2.7 is a sealing element used in pressure washer pump assemblies and high-pressure pumps. Its role is to maintain tightness in the pump’s working section, directly improving pressure stability and limiting water leakage.

MPN / reference: 496036
Dimensions / size: 15×24×5/2.7
Weight: 0.001 kg

APPLICATION

Component used in service work related to sealing the pump section, including:

• replacing the seal in the piston / guide area in the pump head,
• pump refurbishment after prolonged operation,
• eliminating leaks that cause water seepage and unstable pressure,
• periodic service of high-pressure pumps in pressure washers.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Typical signs of wear or damage of the seal/cup seal:

• water leakage around the pump head or piston section,
• drop in working pressure despite a functional nozzle,
• jet pulsation and pressure fluctuations during operation,
• moisture on pump components after downtime or after finishing work,
• accelerated wear of other sealing parts (result of leakage in the section).

HOW TO CHOOSE THE RIGHT PART

Selection should be precise - seals with similar dimensions may differ in profile and application:

• by dimensions: 15×24×5/2.7 (inner diameter, outer diameter, and height/profile),
• by manufacturer MPN / reference: 496036,
• by comparison with the removed part: check dimensions and shape (working profile) before installation.

Accurate fit is critical for tightness, correct pump operation, and seal durability.

COMPATIBILITY

Compatibility should be determined based on the 15×24×5/2.7 dimensions and MPN 496036.
Selecting only “by machine name” is not recommended - correct fit should be confirmed using pump documentation, a parts table, or measurement of the removed component.

[faq]

Will this 15×24×5/2.7 seal fit every 15 mm pump?|Not necessarily. The “15 mm” label is often shorthand. Fit is determined by the full dimensions (15×24×5/2.7) and the part profile. The safest approach is selecting by MPN 496036 or by comparing with the removed part.
How do I measure the seal to select the right replacement?|Measure the inner and outer diameter and the height/profile (here: 15×24×5/2.7). Also compare the working shape with the removed seal, as profile differences may cause leaks.
Can I use an aftermarket alternative instead of the Kränzle part?|Yes, but only if the alternative has identical dimensions and profile and is rated for high-pressure systems. If you’re unsure, selecting by MPN and technical data is the safest option.
