Product Overview
The Ingersoll Rand 47553883001 22356737 Double Lip Seal is a replacement sealing component for compatible Ingersoll Rand rotary screw compressor equipment. Its double-lip design provides two sealing interfaces, helping control lubricant leakage and maintain the intended separation between the lubricated mechanical assembly and the surrounding environment.
Part number 22356737 is identified as a double lip seal with wedge for counterclockwise rotation, designated RD76/102 × 12. The rotational direction is an important selection detail because the sealing geometry must correspond to the intended shaft rotation. A seal with a similar dimensional designation but a different directional arrangement should not automatically be treated as interchangeable.
In a compressor drive or airend assembly, the shaft seal operates where a rotating shaft passes through a stationary housing. The sealing lips maintain the required interface with the shaft, helping retain lubricant while limiting leakage along the rotating surface. The additional lip provides a second sealing interface, although the actual sealing performance depends on the seal construction, installation, and operating conditions.
A damaged or worn double lip seal may cause oil residue around the shaft, visible leakage near the housing, or gradual lubricant loss. Replacing the seal can restore the intended sealing function when the fault is attributable to the sealing element. The shaft surface, housing bore, bearing condition, and installation orientation should also be examined because defects in these areas can cause a replacement seal to leak prematurely.

Working Principle
The 22356737 double lip seal operates at the interface between a rotating shaft and a stationary housing. Its sealing lips maintain contact with the shaft surface, creating a barrier that restricts lubricant from escaping along the shaft and helps prevent external contaminants from entering the protected assembly.
A simplified arrangement is:
Lubricated Compressor Assembly → Double Lip Seal → Rotating Shaft Interface → External Environment
As the shaft rotates, the sealing lips accommodate normal rotational movement while maintaining the contact required for leakage control. The two-lip arrangement provides two sealing interfaces, but the precise function of each lip depends on the seal’s construction and the original equipment design.
The wedge-equipped configuration and counterclockwise designation are significant when selecting a replacement. Directional seal designs may use geometry intended to work with a particular shaft rotation. Installing the wrong variant can compromise the intended sealing behavior even if the replacement appears to fit the shaft and housing.
The RD76/102 × 12 designation identifies the seal’s specified dimensional configuration. Correct installation also requires a suitable shaft surface, an undamaged housing bore, and the orientation specified for the assembly. The designation alone does not establish the seal material, maximum operating temperature, pressure limit, or permitted shaft speed.
During operation, friction and contact at the sealing interface can contribute to wear. Contamination, poor lubrication, excessive shaft movement, and damage during installation may shorten service life. If leakage returns after replacement, the complete sealing arrangement should be inspected rather than repeatedly replacing the seal without identifying the underlying cause.
Role in the Compressor Mechanical Assembly
The 22356737 Double Lip Seal serves as a sealing component within the designated rotating-shaft assembly. It works with the shaft, housing, bearings, and lubrication system to maintain the intended boundary between the lubricated interior and the surrounding environment.

Installation and Maintenance
- Verify the complete part number: Confirm 47553883001 and 22356737 against the installed seal and the compressor’s parts identification.
- Check the rotation direction: Verify that the required seal is the counterclockwise (CCW) variant and that the shaft’s intended rotation matches the application.
- Confirm the seal designation: Compare RD76/102 × 12 with the original component and the specified replacement configuration.
- Identify the leakage source: Determine whether oil is escaping from the shaft seal or from a nearby joint, connection, or other sealing component.
- Shut down the compressor: Follow the approved shutdown procedure and prevent unexpected startup during maintenance.
- Isolate the equipment: Apply the required electrical isolation and pressure-release procedures before accessing the shaft assembly.
- Inspect the shaft surface: Check for scoring, corrosion, grooves, or abnormal wear that could damage the new sealing lips.
- Examine the housing bore: Clean the seal seat and inspect it for scratches, deformation, contamination, or damage from previous removal.
- Install the correct seal: Follow the equipment-specific procedure for rotational orientation, fitting tools, installation depth, and any specified lubrication.
- Protect the sealing lips: Prevent the lips from catching on sharp edges, threads, keyways, or other features during installation.
- Verify the repair: Restore the equipment according to the approved procedure and inspect the shaft area for leakage during the appropriate operating checks.
- Record the maintenance results: Document the part number, rotation direction, observed leakage, shaft condition, replacement date, and post-repair inspection findings.

Technical FAQs
Why is the counterclockwise designation important when replacing the 22356737 seal?
Part number 22356737 is identified as the counterclockwise variant. Directional seal geometry can affect sealing behavior during shaft rotation, so the replacement should match the original configuration and the shaft’s intended direction of rotation.
How does the 22356737 differ from the 22356729 Double Lip Seal?
The 22356737 is identified as a counterclockwise RD76/102 × 12 double lip seal with wedge, whereas the 22356729 is identified as a clockwise RD76/94 × 12 variant. Their directional specifications and dimensional designations differ, so they should not be substituted solely because both are double lip seals.
What can cause oil leakage after installing a new double lip seal?
Potential causes include damage to the sealing lips during installation, an incorrect rotational variant, a scored shaft surface, a damaged housing bore, contamination, or excessive shaft movement. The assembly should be inspected to identify the cause before another seal is fitted.
Does the double-lip design eliminate the need to inspect the shaft and bearings?
No. The sealing arrangement depends on the condition of the shaft, housing, and associated mechanical components. Shaft wear or excessive movement can compromise both sealing interfaces, so these conditions should be checked whenever a leaking seal is replaced.
