PSS HS 2" Shaft Seal 3" 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

fantastic value, ridiculous comfort
This U-shaped full-body pillow does take a minute to fluff up after unboxing—kind of like it’s waking from a long nap—but trust me, the wait is worth it. Once fully awake, it’s soft, breathable, and flexible enough to wrap around you like a clingy sloth that actually improves your sleep. The removable velvet cover is so comfy you’ll consider replacing your wardrobe with it, and yes—it’s washable, because life happens. There’s no weird factory smell, which is always a bonus when you’re about to cuddle something the size of a small adult.
You can use this pillow everywhere: on the bed, couch, floor, or even in the car (preferably not while driving). It excels at supporting your back, belly, hips, and legs, whether you’re pregnant, tired, or just chronically committed to comfort. Perfect for marathon sleep sessions or those “I’ll just close my eyes for five minutes” naps that last three hours.
Quite possibly the best cuddle partner that doesn’t talk back.

Body pillow
They air sealed it. But It came with a lot of empty space through the entire body pillow, Now I have to find stuffing just to make it work.

I’ve lived decades without this pillow… and I regret every single second!
I can’t even overstate how excited I am about this pillow. I’ve only had it for one night, but in that time, it’s completely changed my life. Literally — I sat on my bed with it all day just hugging it and marveling at how I survived adulthood (and procreation years!) without it.
Physically, I’ve been more comfortable in the last 24 hours than I have been for years. And as a bonus, my dogs sleep up against me, which can produce a lot of pressure, but this pillow creates a perfect natural barrier. They seemed to respect it completely — for the first time in three years, I didn’t have a 50lb dog pressing on me all night. Total bliss.
The U-shape supports you in all the right places — back, hips, knees, belly — and the velvet cover is soft, removable, and washable. Honestly, whether you’re pregnant or not, this pillow is a life-changing sleep upgrade. I have no idea how I ever lived without it.

Bumpy & lumpy.
This pregnancy pillow arrived in a surprisingly small box—about the size of a shoe box just a tad bigger—which honestly impressed me considering it’s a full-body U-shaped grey pillow. Once opened, I cut the plastic wrap and let it decompress for a full 24 hours as recommended.
After placing it on my bed to check it out, I noticed the pillow felt lumpy throughout, almost like the filling needs to be manually shifted and positioned to where you want support. That part felt a bit odd and took some adjusting. The outer velvet cover is soft and pleasant to the touch, but unfortunately the pillow itself doesn’t feel very soft once inside the cover. Doesn't give the fully support that I wand and need.
Overall, it does expand to full size and the cover is nice, but the uneven filling and firmness made it less comfortable than I expected for sleeping.

Finally a Cooling Blanket That Actually Works for Hot Sleepers
Size: Queen (90" * 90"）, Color: Luxury Grey, Size: Queen (90" * 90"）, Color: Luxury Grey
I first got to know this brand when they released their cooling pillow. At the time, I was very skeptical because I’ve tried many “cooling” pillows and pillowcases from other brands, and almost all of them failed to stay cool throughout the night. Surprisingly, this brand was the first one that actually worked for me.
Going through menopause has been extremely difficult, especially dealing with the constant heat and night sweats. I kept thinking that if they could somehow use the same cooling technology in a blanket, it would be amazing — and they actually did it.
This blanket has honestly been a lifesaver for me. One side has the cooling fabric while the other side feels more like a regular blanket, so you can switch depending on the temperature or season. I’ve been using a silk comforter before this, and while it was comfortable, it really didn’t help much with overheating at night. This cooling blanket made a noticeable difference almost immediately.
What impressed me most is that the cooling effect doesn’t just disappear after a few minutes. It stays comfortably cool and lightweight through the night without feeling damp or overly thin. Since using it, I’ve actually been tracking improvements in my sleep using my WHOOP device, and over the past 20 days I’ve noticed my deep sleep readings improving consistently.
The blanket also feels well made, soft, and lightweight without feeling cheap. For the quality and performance, I think the price is very fair, especially compared to other “cooling” bedding products that overpromise and underdeliver.
If you struggle with hot sleeping, night sweats, or menopause-related heat issues, I would absolutely recommend giving this a try. It genuinely improved my sleep quality.
