Lasdrop Dripless Shaft Seals

December 15, 2011

Lasdrop Gen II Dripless Shaft Seal, Premium Shaft Seal

Lasdrop dripless shaft seals are the answer for an easily installed replacement to the original stuffing box on nearly any boat. Once installed, there is virtually no maintenance required. The “Original” Bellows and Generation II models will last as long as eight to ten years before servicing, while the DrySeal model will last three to five years before the inner lip seal must be changed. At the service interval, both the Original and Generation II models would most likely require refurbishing of the seal surfaces. In addition, the bellows on the Original model should also be inspected and replaced, if necessary.

Green Solution – Lasdrop shaft seals are the green solution to preventing contaminated bilge water from entering the ocean you are in. Whether you are running a research vessel in Antarctica, a fishing boat in Norway, a world cruising sailboat or a workboat in Maine, keeping the water you run in clean is a good practice. Remember, keeping water out also means keeping engine and drive train bilge water in.

Lasdrop Shaft Seals are manufactured and engineered entirely in the USA. All Lasdrop products are backed by a three year warranty. Each model is easy to install, requires little or no maintenance, and is sold as a complete kit. Installation is easy and straight forward as long as you can access the area where the seal is installed. It will be necessary to disassemble the shaft from the coupling and the shaft will need to be slid back far enough to remove the original stuffing box.

Lasdrop incorporates injection ports for water lubrication in vessel applications where speeds are over 10 knots. Lasdrop builds single injection port shaft seals from 3/4″ to 1-1/8″ and offers 2 (dual) injection ports installed for shaft sizes from 1-1/8″. Built for any budget and boat, Lasdrop supplies 3 different levels of dripless shaft seals.

Good – the Lasdrop DrySeal is a compact, economical lip seal designed for quick and easy installation. This option offers a lip seal that is in constant low friction contact with the propeller shaft, preventing water from entering your vessel. The simple, affordable solution to a leaking tired stuffing box.

Better – the Lasdrop Original “Bellows” seal is a face seal that features a vibration absorbing bellows, ideal for use on sailboats and workboats. Specially balanced for smooth rotation, this model utilizes a 316 stainless steel and carbon graphite for its sealing surfaces. These modifications and materials result in a dripless shaft seal that lasts twice as long as the Lasdrop DrySeal.

Best – the Lasdrop Gen II is a culmination of more than a quarter century of experience in shaft seal design. An exclusive feature that makes it the premier shaft seal are a unique ball-bearing drive system that allows the seal ring to “float” and remain in constant contact with the carbon graphite seal surface, resulting in a seal that’s impenetrable to water.

    I have a 42 ft work / fishing boat with a 1&3/4″ shaft, if I order a gen II model how much will it cost. 18 to 20 knots running but a lot of idle speed trolling.
    Thanks

    I intend to install a dripless seal in my sailboat. I have a 12hp BMW single cyl diesel.
    The shaft is 1″ and the shaft-log is 1.75″o.d.
    It looks like the Lasdrop Bellows 89769 – AR100VI is the model I should use. Can you confirm I am about to buy the correct model for my application?
    I’m also comparing it with the PSS Shaft-Seal product. How does one make a comparison, other than the fact the PSS is less expensive? Other than that, they seem very similar!!!
