PSS Shaft Seal 1" Shaft 1-¾" Tube

The PSS Shaft Seal 1" Shaft 1-¾" Tube is essential for a reliable through-hull shaft installation on cruising or fishing vessels. Many boaters often overlook the maintenance of shaft seals until water begins to seep into the bilge, making this product a critical upgrade for any serious boat operator.

This PSS shaft seal features a unique dripless design that prevents the constant weeping associated with traditional packing boxes. It is engineered to keep saltwater and debris out while allowing controlled lubrication flow, thus protecting the shaft log and bearing system from corrosion and potential failure. The elastomer sealing components are designed to withstand thermal cycling and vibration loads, ensuring a durable barrier against salt intrusion.

Ideal for both cruising yachts and commercial fishing vessels, this shaft seal accommodates standard inboard drive systems. Whether you're repairing an older offshore cruiser or refitting a workboat, this component provides the performance and longevity needed for reliable operation.
