Pressure Housing -vs- Bellows Hose

Gen2 creates compression through the innovative pressure housing, eliminating the need for a bellows hose. The Pressure Housing offers a much longer life span when compared to a bellows, reducing maintenance over the life of your seal.

Integrated Bearing Design

The Gen2 integrated water lubricated bearing allows the seal body to self-align following the shaft insuring proper face seal alignment.  ALL Lasdrop bearing housings have tolerances within 0.001 of an inch.

Integrated Clamping System

The Gen2 Pressure Housing secures to the shaft through a simple integrated clamping system. This eliminates the need for set screws – which can potentially damage the shaft and slide after their first use resulting in a less secure and stable seal.

Gen2 Shaft Seal

The Lasdrop Gen2 Shaft Seal is a commercial grade mechanical face seal designed for long lasting installation in some of the harshest conditions. It is made specifically for commercial and heavy personal marine use and is one of the most premium seals on the market today.

Sizes and Specifications

Gen2 Sizes

Lasdrop Gen2 sizes range from 1″ up to 5″ (30mm to 130mm).  Gen2 shaft seals can be fully customized based on your specifications. Please see our standard sizing below and contact AB-Marine if you have any questions or need any assistance in sizing the correct shaft seal for your job.
