PSS Dripless Shaft Seal — 1-1/4" Shaft × 2-1/4" Stern Tube
The PSS 02-114-214 is a Type A mechanical face-type dripless shaft seal for inboard vessels running a 1-1/4" propeller shaft and a 2-1/4" to 2-3/8" stern tube. A stationary carbon flange presses against a rotating stainless-steel rotor to form a positive seal — no drip, no packing adjustment, no shaft wear from a conventional stuffing box.
Key Specifications
- Shaft diameter: 1-1/4"
- Stern tube (shaft log) OD: 2-1/4" to 2-3/8"
- Seal type: PSS Type A mechanical face seal
- Sealing flange: carbon
- Rotor: stainless steel (approx. 2.875" OD)
- Compression maintained by bellows
- Uncompressed assembly length: approx. 7.5"
- Recommended compression: approx. 3/4"
- Stern-tube cuff length: approx. 1.5"
- Part number: 02-114-214 / 02114214
- UPC: 839662007177
Compatible Applications
- Inboard marine propulsion systems with a 1-1/4" propeller shaft
- Stern tubes measuring 2-1/4" to 2-3/8" OD at the bellows connection point
- Both shaft diameter and stern-tube diameter must be confirmed before ordering — do not select by shaft size alone
When to Replace
- Bellows shows aging, cracking, or deterioration (below-waterline component — inspect regularly)
- Sealing faces are damaged or no longer seat correctly
- Persistent leakage develops at the seal interface
- Hose connections, clamps, or rotor set screws show corrosion or looseness
Installation Notes
- Position the stainless rotor on the shaft ahead of the carbon flange to compress the bellows to the correct preload
- Clean and inspect carbon and stainless sealing faces before assembly
- Secure rotor set screws and verify vent/water-feed routing per current PSS installation instructions
- Verify available shaft space against the 7.5" uncompressed assembly length before ordering

Parts Desk Insights
For the 02-114-214, the shaft measurement is only half the fitment check. This version specifically pairs a 1-1/4" shaft with a 2-1/4" to 2-3/8" stern tube — measuring the shaft log OD before ordering is the safest way to avoid a mismatch. Also confirm you have at least 7.5" of clear shaft space between the cutlass bearing and the coupler before the rotor is installed; tight drivetrains on smaller inboards can make this a close fit.
