PSS Hose Barb Plug

  • Description

    This is a plug for the PSS Shaft Seal hose barb. If your boat will not exceed 10 knots under power then the PSS Shaft Seal does not require positive water feed. The PSS Shaft Seal can simply be "vented" or you can use this plug in place of the hose barb that's inserted into the carbon stator.

    "Burping" The PSS Shaft Seal

    You will also be required to "burp" the PSS Shaft Seal whenever there is air trapped inside. Simply pull back on the carbon stator, separating it from the stainless steel rotor. This will cause a quick mist of water to spray out.


    If your boat will exceed 10 knots under power then it is required that a positive water supply be plumbed to the PSS Shaft Seal for the purpose of lubricating and cooling the seal faces.

Get rid of that pesky hose

I recently purchased the PSS hose barb plug to remove the breather hose for my dripless shaft seal. Especially if it’s mounted on a sailboat that will never see speeds beyond 10 knots under power, can do away with the breather hose altogether. And not worry about making sure the hose is above the waterline to prevent flooding. You just have to remember and burp the seal when you put the boat in the water.
