Ingersoll Rand Vent Replacement - 70243936

Maintain proper crankcase ventilation and dependable compressor operation with the Ingersoll Rand Vent Replacement - 70243936, a frame vent designed for compatible Ingersoll Rand single stage reciprocating compressors. This vent allows pressure inside the compressor crankcase to escape during the compression process, helping prevent pressure buildup within the oil filled pump housing. Replacing a clogged, cracked, damaged, or missing vent can help maintain proper crankcase breathing, protect seals and internal components, and support reliable compressor performance.

  • Relieves Crankcase Pressure: Allows excess air pressure to escape from inside the compressor crankcase during normal operation.
  • Supports Proper Pump Operation: Helps prevent unwanted crankcase pressurization that can interfere with lubrication and sealing performance.
  • Compatible with SS3 and SS5 Compressors: Used on compatible Ingersoll Rand SS3 and SS5 single stage reciprocating compressor applications.
  • OEM Compatible Replacement: Built as a replacement for Ingersoll Rand part number 70243936 and installs as a threaded frame vent on compatible compressor pumps.

Help maintain proper crankcase pressure and dependable pump operation with the Ingersoll Rand Vent Replacement - 70243936, a practical replacement vent for compatible Ingersoll Rand reciprocating compressors.

Frequently Asked Questions

Is the 70243936 vent compatible with my Ingersoll Rand compressor?

The 70243936 is an Ingersoll Rand frame vent / crankcase breather cap used on compatible single-stage reciprocating air compressors. Published fitment specifically includes SS3 and SS5 compressors. Compatibility should be verified by matching 70243936 in your compressor parts manual and confirming the model, serial number, crankcase vent location, thread or mounting configuration, and installed part number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 70243936 vent do?

The 70243936 vents pressure from inside the compressor crankcase during operation.

As the reciprocating compressor runs, internal movement can cause pressure fluctuations inside the oil-filled crankcase. The vent allows this pressure to escape so the crankcase does not become unnecessarily pressurized.

The vent helps:

  • Relieve crankcase pressure
  • Allow the compressor crankcase to breathe
  • Support proper crankcase ventilation
  • Reduce unnecessary internal pressure buildup
  • Help protect crankcase seals and gaskets
  • Support reliable reciprocating compressor operation

Where is the 70243936 vent located on the compressor?

On documented SS3 and SS5 applications, the 70243936 is located on the back side of the compressor pump near the flywheel.

Its location allows it to communicate directly with the crankcase and relieve internal pressure as the compressor operates.

The exact location can vary on other compatible compressor configurations, so use the machine's parts diagram to confirm the correct installation point.

What are the signs that the 70243936 vent needs replacement?

Common signs include:

  • Vent is cracked or broken
  • Breather cap is missing
  • Vent is clogged with dirt or oil residue
  • Internal breather passages are obstructed
  • Cap no longer fits securely
  • Visible deterioration
  • Excessive crankcase pressure
  • New oil seepage around seals or gaskets
  • Heavy contamination around the vent area
  • Replacement is required during pump service

A damaged or heavily contaminated breather should not be ignored because proper crankcase ventilation is important for reciprocating compressor operation.

Is this an OEM part?

This is an OEM-equivalent replacement vent designed to meet the same performance standards as the original Ingersoll Rand vent.  

How difficult is it to install?

Replacing the 70243936 is generally a simple routine maintenance task, especially on SS3 and SS5 compressors where the vent is accessible on the back side of the pump near the flywheel.

Before service, the compressor should be:

  • Fully shut down
  • Electrically locked out
  • Completely depressurized
  • Cooled to a safe working temperature
  • Verified so it cannot automatically restart

Installation typically involves removing the existing breather, checking the opening for contamination, installing the replacement 70243936, and confirming that it is secure without damaging the vent or its mounting point.

Avoid allowing dirt or debris to fall into the open crankcase while the vent is removed.

Do you carry other parts for Ingersoll Rand?

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Ingersoll Rand equipment. If you don’t see what you need, just ask and we’ll help you find it.  

How do I know which oil to use in my Ingersoll Rand compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Ingersoll Rand Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
