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.

Nice office chair!
Color: Dark
This is a nice office chair. All of the features work as stated. I would say the seat is slightly more firm than I prefer, but comfort is subjective. The pleather is soft and I like that the arm rests fold out of the way.

This Marsail Executive Office Chair Is Excellent For A Comfortable And Polished Desk Setup
Color: Dark
This Marsail executive office chair is excellent, and it brings together comfort, support and a clean professional look in a very practical way. The PU leather has a smooth, polished presence that suits a desk chair well without looking overly bulky. I appreciate that the design includes flip-up armrests, a height-adjustable seat, swivel movement and rolling mobility in one complete chair. The cushioning gives the chair a substantial seated feel, while the back design adds support without making the chair look heavy. It is an office chair that feels thoughtfully built for daily desk work, focused tasks and general seated comfort. The chair arrived securely protected and in very good condition, with the main parts kept in place well through transit. The PU leather surfaces looked clean, smooth and free from distracting marks when unpacked. The base, wheels, armrests, backrest and hardware all appeared properly finished and ready for assembly. Nothing about the chair parts looked loose, flimsy or poorly handled when it arrived. The included components were organized. The appearance of this chair is one of its strongest qualities because it has a dark, sleek and professional style. The chair fabric gives it a refined executive look, while the breathable mesh center keeps the backrest from appearing too solid or oversized. The flip-up armrests blend into the design nicely and add a cleaner profile when raised. The chair has a balanced shape, with a supportive back, plush seat and wide base that all work together visually. It looks modern without being too flashy, which makes it easy to place with different desks and work areas. Functionality is where this chair becomes especially practical because it is easy to put together and simple to adjust. The height adjustment works well for getting the seat into a comfortable position at a desk. The swivel and rolling movement make it easy to shift, turn and reach without the chair feeling stiff. The reclining range and gentle rocking function add a useful option for leaning back during breaks. The flip-up armrests are especially convenient because they allow the chair to tuck under a desk more easily and create extra freedom of movement when needed. The value is strong because this chair offers several useful features in one well-rounded design. The thicker cushioning, contoured support, PU leather surface, breathable backrest, reclining function and flip-up armrests all add to its usefulness. The sturdy base and stated 300-pound support rating also give it a more dependable feel than a basic desk chair. It provides the comfort expected from an executive chair while still offering space-saving details that make it practical. For the features, comfort and overall build, it delivers a very complete office seating option. I highly recommend this Marsail executive office chair for anyone wanting a comfortable, polished and functional desk chair. It is excellent, easy to put together and built with enough adjustability to support different work habits. The combination of plush cushioning, ergonomic shaping, smooth movement and flip-up armrests makes it especially useful for a home office or workspace. I also like that it has a professional look without sacrificing everyday convenience. It is a strong choice for dependable seating that looks good, works well and offers solid comfort.

Comfortable for daily use!
Color: Dark, Color: Dark
After using this chair for work and general desk time, I think it does a nice job balancing comfort, adjustability, and overall build quality without feeling overly bulky or cheap. It feels designed for people who spend long stretches at a desk and want something supportive but still comfortable enough to relax in occasionally. Assembly was straightforward. The instructions were clear, the hardware was organized well, and all the holes lined up properly during setup. I put it together by myself in around 20 minutes without needing extra tools. Once assembled, the chair immediately felt sturdy and stable rather than wobbly. The overall quality is solid for this price range. The PU leather has a soft feel and doesn’t have the stiff plastic-like texture some office chairs use. The stitching looks clean, the armrests feel secure, and the rolling base moves smoothly across the floor. The chair also feels durable overall, especially around the frame and base where cheaper chairs sometimes feel weak or shaky after a few weeks of use. It's very comfortable. The seat cushion is thick and supportive without feeling overly hard, and it stays comfortable during long work sessions. I’ve spent multiple hours at a time sitting in it without constantly adjusting positions or feeling pressure points. The mesh section in the backrest also helps airflow a bit, which keeps it from feeling too hot during extended use. The lumbar support is great. The backrest naturally follows the curve of your spine and provides good lower back support while still feeling relaxed enough for casual sitting. I also liked the higher back design since it supports the upper back and shoulders well during longer periods at the desk. The flip-up armrests ended up being more useful than I expected. They make it easy to slide the chair under the desk when not in use, and they also give more room if you like sitting cross-legged occasionally. Solid chair overally. It has a good mix of comfort, support, ease of use, and practical features without feeling overpriced.
