PSS HS 25mm Shaft Seal 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 dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

Dog toy that lasts.
Size: 5 Pack
I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room!
I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak.
The crinkle sound is a huge bonus; it really keeps him engaged.
The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around.
For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.

Great toy that stands up to tough dogs
Size: 5 Pack
When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Solid dog toys HOWEVER...
Size: 5 Pack
Got these toys for our collie-retriever. He loves them and plays with them a lot and will even get them out in the middle of the night to play with them. Since there's no stuffing you can't throw them very far but they are good for tug-of-war and really soft. The one downside, while they techically are durable and hold up to rigorous chewing, they are not impervious as our little man finally disembowled Mr. Lion after a few months of playing with him. (Serated the lining with his teeth.) Still highly recommend.
