PSS HS 2-1/4" Shaft Seal 3-1/2" Stern TubeThe PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller
The PSS (Packless Sealing System) shaft seal is designed as a maintenance free alternative to the traditional packing glands and stuffing boxes. The PSS does not require a greaser drip to lubricate the shaft, if does not require packing and it doesn't need adjusting or maintaining once installed. The design of the PSS seal makes it 100% watertight when installed correctly to prevent water leaking into the bilge, and it also protects the propeller shaft from wear. A mechanical seal is created between a rotating stainless steel 316 rotor and a stationary carbon/graphite stator. The stator attaches to a convoluted rubber bellow which attaches at the other side to the stern tube (shaft log) with the use of hose clamps. The rotor secures to the prop shaft to complete the installation. Because the bellows can compress and expand, fore and aft movement of the shaft caused by propeller thrust does not affect the seal created. The static carbon stator is purposely bored larger than the shaft diameter to allow for any problems caused by misalignment and vibration. Under normal operating conditions, the carbon stator and the stainless steel rotor should never need replacing, and nor should the two nitrile O-rings used to seal the rotor to the shaft. This PSS seal features a rubber bellows which is designed with durability, strength and elasticity all in mind. Seals are available in a wide range of sizes for different propeller shafts and stern tube diameters. All PSS shaft seals are certified by ABS, Bureau Veritas and RINA.Shipping Notes

My Unstoppable Journey: How 'Can't Hurt Me - Clean Edition' Changed My Life Forever!
Format: Hardcover
As an avid reader and self-improvement enthusiast, "Can't Hurt Me: Master Your Mind and Defy the Odds - Clean Edition" by David Goggins has undoubtedly been the most transformative book I've ever encountered. From the very first page, Goggins' unfiltered honesty and relentless pursuit of greatness struck a chord deep within me. His journey from a troubled past to becoming a Navy SEAL and an ultra-endurance athlete is nothing short of awe-inspiring, and it motivated me to confront my own limitations and push past my comfort zones.
What truly sets the clean edition apart is its accessibility to a wider audience, without compromising the book's raw power. Goggins' story of overcoming immense adversity and mental hurdles resonates deeply, and the absence of explicit language only strengthens the impact of his words. Reading his struggles, failures, and ultimate triumphs, I found myself on an emotional rollercoaster, laughing, crying, and cheering him on with each turn of the page. But more importantly, the book empowered me to embrace discomfort, tackle my fears, and cultivate an unbreakable mindset. Thanks to Goggins' candid narrative and practical tools, I now approach challenges with newfound tenacity, and I'm well on my way to achieving goals I once considered impossible. "Can't Hurt Me - Clean Edition" is a true masterpiece that has forever changed my perspective on what's achievable when we harness the power of our minds.

Buena calidad
Format: Hardcover, Format: Hardcover
Es de pasta dura. El material de las hojas se siente de buena calidad. El tamaño de las letras es adecuado. Mi perro lo mordió un poco por eso en la foto sale así. En cuanto al libro, es bastante biográfico, y deja las enseñanzas del autor.
