The PSS Shaft Seal is the number one selling marine mechanical seal worldwide and is installed as standard equipment by many of the worlds most reputable boat builders / yards. The PSS Shaft Seal is also recognized as the premiere retrofit (aftermarket) seal on the world market. Certified by Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages and value of installing the PSS as it eliminates the maintenance, constant adjustment & cost associated with traditional packing type glands. Aside from these benefits, the PSS Shaft Seal helps to eliminate water in the bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal can be easily retrofitted and is available for shafts ranging from 3/4" (20mm) to 6" (150mm).

The PSS Shaft Seal is a mechanical face seal that is created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This compression (pre-load) maintains contact between the faces and allows the PSS to compensate for the thrust from the propeller. The carbon flange is bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two o-rings that are recessed into the bore of the collar. These o-rings rotate with the shaft and stainless steel rotor and do not experience wear during operation.


**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration. PYI suggests as preventative maintenance that the PSS bellow be replaced in six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."

Bellows may need to be more frequently inspected in an environment where non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.

The Maintenance Kit includes the items you need to properly maintain your PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings, five (5) set screws, four (4) new hose clamps and an allen key.

Definitely keeps your hands warm !!
Color: Black
These fit nicely on a H.D. Road King. If you bike has heated grips you can drive in 30 deg F weather with only a thin pair of leather gloves. Update: They kept our hands toasty with the heaters on Level 2 and just wearing a thin pair of leather gloves (for grip) while riding in temps down in the low 30's, high 20's. I would definitely recommend these... the photo in the ad is pretty indicative of how they fit on handlebars. They're really designed for ATV's that have no turn signal lamps on the handlebars. Without modification, they do cover the handlebar mounted turn signals on a Sportster, but not on a Roadking. The draw string that seals the mittens around the handlebar could have a more positive grip to stay closed... we wound up double tying it around bar and that works great. The thing we like most aside from how warm they are (the lining feels great)... is that the cuffs are fairly rigid and don't collapse when you take you hands out (like the photo) which makes it super easy to pull you hands out and put 'em back in again. That's really important at a stop light, but even more important when flying down the road at highway speeds... you just can't afford to be fooling around trying to thread your hands and a coat sleeve back into mittens that are limp and flop down closed when you take you hands out... I hope this help... be safe !!

If your hands are cold or wet after knowing these handlebar covers exist, well, that’s on you.
Color: Black
These atv gloves, mitts, handlebar covers, whatever you want to call them are a fantastic value. I was honestly surprised at the quality of construction. They have a soft comfortable cotton lining that seems to really hold heat from your hands. The cordura outside is super strong and the seams are very well done. There is a zip along the inside bend to allow for expansion over bigger controls to to allow for use with heavier gloves. (Just leave it unzipped) The draw string to tighten and secure the end to the handlebar is easily to operate and keeps everything snug and in place. It takes about 5 seconds to put each side on or take off. The draw string on the covers is about 5 times longer than necessary and I ended up cutting a foot or so off. The down side of these is how snug a fit they have to the contour of the handlebars and controls. The material is pretty stiff, so you have to be careful. I was getting back on my Polaris 570 after stopping and I typically just leave my fourwheeler in high, so when I leaned forward on my handlebars the covers were stiff enough to push my throttle. Thank goodness nothing was in front of me, or was around to witness my panic. Ha. If I turn to sharply I have to be mindful of the material pressing against my hand and thus the throttle. It does Unzip at the elbow of the covers, but the seams are so stiff there is still resistance. I wish there was a softer material at the hand and bend, however the rigidity really makes it easy to slide your hands/arms (5’8” with alligator arms and they just about come to my elbows) in and out easily, even with a heavy coat. They are indeed 100 waterproof, as unfortunately tested on 2 occasions. They are 112% windproof and I can comfortably ride all day at 35-40 degrees with no gloves(I live in west Alabama so sub 40 degrees is cold for me.) They have been an absolute game changer for the early morning drive in at the hunting club. They are a little stiff for sharp turns on wooded trails, but I expect they will soften with use. Be mindful of the throttle and KNOW YOUR CONTROLS as they will be covered, but do yourself a favor and get these. If your hands are cold driving your fourwheeler after knowing these exist, well, it’s your own fault.

Product still holding up
Works great. Protects hand from wind and sticks. The cell phone pocket doesn't hold large phones, but I don't think it's even necessary.

Can hit the brake
Color: Black
Works well to keep the cold off your hands. Unfortunately at higher speeds, the wind resistants can actually cause them to hit the front brake. Was riding home doing almost 80 and got a wiff of burning brakes....pulled over and they were smoking pretty bad.
