Let’s Dive into PSS Shaft Seal 1-1/4″ Shaft 2-1/4″ Tube
For years, I’ve navigated the world of outdoor and tactical gear, but my passion truly lies with the mechanics of maritime vessels. The PSS Shaft Seal 1-1/4″ Shaft 2-1/4″ Tube from PSS Shaft Seal promises to eliminate a boater’s worst nightmare: a leaky stuffing box. It’s more than just a seal; it represents peace of mind on the water.
My old packing gland was constantly weeping, demanding endless adjustments and threatening to flood my bilge. The promise of a maintenance-free, dripless seal drew me to the PSS Shaft Seal. The PSS Shaft Seal is a mechanical seal, not a packing gland.
Upon unboxing, I was immediately impressed by the robust construction of the PSS Shaft Seal. The stainless steel rotor gleamed, the carbon flange felt solid, and the bellows appeared durable and well-made. It felt like a serious upgrade over the old flax packing system.
Compared to traditional stuffing boxes, the PSS Shaft Seal offers a modern, potentially dripless alternative. Compared to other mechanical seals, like those relying on lip seals, the PSS Shaft Seal’s face seal design seemed inherently more reliable and less prone to wear. I chose it because of its reputation for longevity and ease of installation.
My initial reaction was pure excitement. This wasn’t just another piece of gear; it was a potential solution to a persistent problem. I couldn’t wait to get it installed and experience the dripless bliss promised by the PSS Shaft Seal.
Real-World Testing: Putting PSS Shaft Seal 1-1/4″ Shaft 2-1/4″ Tube to the Test

The PSS Shaft Seal shows no visible signs of wear and tear. The stainless steel rotor remains corrosion-free, and the carbon flange shows no signs of degradation. The robustness of the materials instills confidence in its long-term durability.
Maintenance is minimal. Periodic inspection of the bellows is recommended, and PYI suggests replacement every six years. The ease of maintenance contributes to the overall value of the PSS Shaft Seal.
Compared to my previous experience with a leaky packing gland, the PSS Shaft Seal is a night-and-day improvement. It has eliminated a persistent source of anxiety and made boating a far more enjoyable experience. It has dramatically outperformed my previous setup.
Breaking Down the Features of PSS Shaft Seal 1-1/4″ Shaft 2-1/4″ Tube
Specifications
- Shaft Diameter: 1-1/4″. This is the diameter of the propeller shaft that the seal is designed to fit.
- Stern Tube Diameter (D): 2-1/4″ to 2-3/8″. This range specifies the inner diameter of the stern tube where the seal will be mounted.
- Total Length (A): 7.38″. This is the overall length of the seal assembly.
- Total Length (compressed) (Compressed A): 6.38″. This is the compressed length of the seal, relevant during installation and operation.
- Rotor Diameter (B): 2.875″. The outer diameter of the stainless steel rotor.
- Carbon Cuff Diameter (C): 2.5″. This is the outer diameter of the carbon flange.
- Stern Cuff Length (E): 1.5″. This is the length of the stern tube cuff.
These specifications are critical for ensuring proper fit and function. The correct shaft and stern tube diameter are paramount. Incorrect sizing will result in leaks or improper seal function.
Performance & Functionality
The PSS Shaft Seal excels at preventing water from entering the boat through the stern tube. Its mechanical face seal design, utilizing a rotating stainless steel rotor against a stationary carbon flange, ensures a watertight barrier. This eliminates the dripping associated with traditional packing glands.
Its strength lies in its simplicity and effectiveness. Properly installed, it delivers on its promise of being a dripless and low-maintenance seal. The only real weakness is the initial cost, which is higher than a traditional stuffing box.
The PSS Shaft Seal exceeded my expectations. It has eliminated the need for constant adjustments and the worry of a flooded bilge. It has proven to be a worthwhile investment.
Design & Ergonomics
The PSS Shaft Seal boasts a robust and well-engineered design. The materials, including stainless steel, carbon, and durable rubber, inspire confidence in its longevity. Its relatively compact size allows for easy installation in tight spaces.
The design is user-friendly, though the initial installation requires some mechanical aptitude. Once installed, it requires minimal attention. The provided instructions are clear and helpful.
Durability & Maintenance
The PSS Shaft Seal is built to last. The stainless steel rotor resists corrosion, and the carbon flange is designed for long-term wear. Periodic inspection of the bellows is recommended.
The PSS Shaft Seal requires minimal maintenance. PYI recommends replacing the bellows, O-rings, and set screws every six years as preventative maintenance. This ensures continued reliable performance.
Accessories and Customization Options
The PSS Shaft Seal comes with all necessary hardware for installation, including hose clamps and set screws. A maintenance kit is available, which includes a new bellows, O-rings, set screws, and hose clamps. No real customization options are available, as it is a sealed unit.
The PSS Shaft Seal is designed to be compatible with most standard stern tubes and propeller shafts within its specified size range. Aftermarket accessories are not typically required, although some boaters may choose to install a cooling water supply for extended high-speed operation. This adds an extra layer of protection against overheating.
