The 22314348 Ingersoll Rand OEM drive coupler is the OEM-issued coupling element used across the Ingersoll Rand higher-output portable rotary screw air compressor family, including the HP, XP, and larger P-series airend platforms. It transmits torque from the drive motor to the airend, compensates for minor angular and parallel misalignment, isolates vibration, and protects bearings, seals, and shafts from torsional shock.
Key features and benefits
- OEM-issued Ingersoll Rand part for the higher-output portable airend platform
- Elastomer flex element absorbs torsional shock and damps vibration
- Sized for higher-CFM and higher-pressure airend service across the HP, XP, and larger P-series lineup
- Lubrication-free design with no service ports or grease intervals
- Direct fit replacement that restores factory balance and alignment behavior
Functional design and performance
The 22314348 links the drive motor to the compressor airend through a flexible elastomer interface. The element absorbs torsional pulsations from the engine and isolates vibration before it reaches the airend bearings. By accommodating small parallel and angular shaft offsets, the coupler reduces stress on rotating assemblies and stabilizes compressor performance across varied load cycles.
Applications and compatibility
The 22314348 is the OEM drive coupling for the Ingersoll Rand higher-output portable rotary screw air compressor family. The Ingersoll Rand factory parts manual (book 22442842, page A-80) documents 22314348 as the drive coupling on the XP185 airend assembly, and the same part is used across related models in the higher-output portable lineup, including the HP185, HP220, XP200, P250, and P260.
The Ingersoll Rand portable compressor line uses several drive coupling part numbers across model years, airend revisions, and engine options. Because of this, confirm 22314348 against your machine’s parts manual, the unit’s serial-number plate, or by calling Stark Industrial Products at (903) 768-1111 with the unit’s serial number for fitment verification before ordering.
Important fitment note: The 22314348 fits the higher-output airend platform shared by the HP, XP, and larger P-series portables. It does NOT fit the standard P185 airend, which uses Ingersoll Rand part 36865012. Verify your model designation, including any X or HP prefix, before ordering.

Installation overview
Verify shaft and bore are clean and burr-free, and inspect key seats for wear or damage. Align driver and driven hubs to the manufacturer’s parallel and angular limits. Seat the elastomer element fully into both hub jaws and torque mounting hardware to specification in a cross pattern. After start-up, confirm vibration falls within baseline and re-check fasteners after the first hours of operation.
Why Ingersoll Rand OEM matters
The 22314348 is the part number issued by Ingersoll Rand for the higher-output portable rotary screw airend platform. An OEM-issued coupler is sized and balanced to the airend it serves. Using the OEM part keeps the rotating assembly within factory balance limits, supports the engine-to-airend torsional model the compressor was designed around, and maintains warranty alignment on covered assemblies.

Frequently asked questions
What Ingersoll Rand models does the 22314348 drive coupler fit?
The 22314348 is the OEM coupling element on the Ingersoll Rand XP185 airend, documented as the drive coupling on page A-80 of factory parts manual book 22442842. The same part is used across related models in the higher-output portable family, including the HP185, HP220, XP200, P250, and P260. Because this product line uses several drive coupling part numbers across model years and engine options, confirm fit against your machine’s parts manual or call Stark Industrial Products at (903) 768-1111 with the unit’s serial number.
Does the 22314348 coupler fit the standard P185 air compressor?
No. The Ingersoll Rand P185 airend uses a different drive coupling, part number 36865012. The 22314348 fits the higher-output airend platform shared by the HP185, HP220, XP185, XP200, P250, and P260. Verify your machine’s exact model designation before ordering.
Does this drive coupler require lubrication?
No. The elastomer element is a lubrication-free design and runs in a dry installation. Inspect the element during scheduled compressor maintenance for cracking, hardening, or chunking.
How long does the 22314348 coupling element last?
Service life depends on duty cycle, ambient temperature, and alignment quality. Replace at the first sign of elastomer cracking, hardening, or loss of torsional response, or as a preventive item during airend service intervals.
Does Stark Industrial Products ship same-day?
Yes. In-stock units ship the same day. Stark Industrial Products operates 24/7 and can be reached at (903) 768-1111.
