Lasdrop is able to satisfy any shaft seal application with our five different drip-less models: Elite, DrySeal, Gen II, Bellows and the TriSeal. Each model is easy to install requires little or no maintenance and is sold as a complete kit - all back by a three year warranty. Our products are used both worldwide in commercial, recreational and transportation vessles by owners who demand durability and reliability.

Lasdrop Shaft Seals are manufactured and engineered by Nautical Specialities entirely in the USA using only the highest grade materials. We utuilize advanced engineering and design to produce the finest shaft seals available. Our goal is to ensure water stays outside your vessel.


 Products

  • Lasdrop Gen II
    The Gen II offers 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....

  • • The Gen II uses a 316-marine grade stainless steel spring to provide pressure to the seal surfaces. Together, the spring and seal ring rotate along with the shaft, and remain secured in the Clamp/Pressure housing. 

    • The Clamp/Pressure housing is secured to the shaft without the use of set screws preventing galling or damage to the shaft.

    • Dual u-cup seals, which also rotate on the shaft, are seated inside of the seal ring and prevent the passage of water to this point. 

    • The friction ring assembly is constructed of a durable copolymer housing protecting the carbon graphite friction ring and also incorporating a water lubricated bearing maintaining correct alignment to the shaft.

    • Each kit includes AWAB hose clamps that are made of 316 stainless steel with rolled band edges to eliminate risk of damage to the hose. The non-perforated band provides twice the tensile strength of a regular clamp.

    • Available in shaft sizes of 1 1/8” – 5” (30mm – 150mm) in diameter.

    • All units have dual water injection ports including necessary hardware.

    • Rated “Best” by Powerboat Reports.
  • Lasdrop Elite
    The Lasdrop Elite is a compact, lip seal designed for quick and easy installation. The lip seal, made specifically for marine use, is in constant low friction contact with the propeller shaft, preventing water from passing in your vessel....

  • • Split-face plate makes it easy to replace inner lip seal with an optional back-up seal without the need for special installation tools.

    • Seal housing is constructed of a durable copolymer with built in water lubricated bearing insuring proper alignment to the shaft. 

    • Seal Case encompassing back-up seal that rotates freely on the shaft until replacement is needed.

    • Utilizes Trident VHT Blue Silicone polyester reinforced hose. 

    • Available in shaft sizes of 7/8” to 8” (22mm to 203mm) in diameter with stern tubes of up to 12” (305mm) in diameter. Flange adapters available.
  • Lasdrop DrySeal
    The Lasdrop DrySeal is a compact, economical lip seal designed for quick and easy installation. The lip seal, made specifically for marine use, is in constant low friction contact with the propeller shaft, preventing water from passing in your vessel....

  • • Split-face plate makes it easy to replace inner lip seal with an optional back-up seal without the need for special installation tools.

    • Seal housing is constructed of a durable copolymer with built in water lubricated bearing insuring proper alignment to the shaft. 

    • Optional Back-up seal rotates freely on the shaft until replacement is needed. 

    • Each kit includes AWAB hose clamps that are constructed of 316 stainless steel with rolled band edges to eliminate risk of damage to the hose. The non-perforated band provides twice the tensile strength of a regular clamp.

    • Available in shaft sizes of 3/4” – 8” (20mm – 200mm) in diameter with stern tubes up to 12” in diameter.

    • All units have dual water injection ports including necessary hardware. For ¾ to 1” seals, dual port available upon request.
  • Lasdrop Bellows
    The "Bellows" 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....

  • • The seal ring is 316 stainless steel, set in a counter bore in the assembly, eliminating metal to metal contact and risk of electrolysis.
    • The clamp ring assembly uses two clamps for maximum strength to secure to the shaft. This provides proper balancing, and also prevents galling and or damage to the shaft.
    • To insure the “O” ring is not damaged from a key way or burrs during installation, it is assembled to the shaft after the assembly reaches its final location. 
    • ARMORFLEX bellows we utilize are second to none. This product is constructed of silicon rubber, hand wrapped with three layers of fiberglass on the inside. The unit is then vulcanized, combining superior strength and durability with unsurpassed resistance to heat and fuels. This type of construction also prevents rotting or delamination.
    • Each kit includes AWAB hose clamps that are made of 316 stainless steel with rolled band edges to eliminate risk of damage to the hose. The non-perforated band provides twice the tensile strength of a regular clamp.
    • Available in shaft sizes of 3/4” – 8” (100mm – 200mm) in diameter with a stern tube of up to 10 ½”. We can accommodate a stern tube flange of up to 18”.
    • All units have dual water injection ports including necessary hardware. For 7/8” to 1” seals, dual port available upon request.
    • Rated “Best” by Powerboat Reports.
