Part Number: 07-HYV-ENTKIT
PYI is now offering the Taco Hy-vent for sail boats and other low speed watercrafts. This nickel platted brass vent is to be installed at the end of the vent line. It is a float style vent / valve that will allow air out, however, restrict water flow in that direction (if any water or backflow is to come up the line from the seal, the vent will close off, keeping the water from entering the engine room). Once the water flow subsides, the float will open allowing air to freely vent. This product is a great option to maintain an air free system and ensure the engine room stays dry in the event of back flow (from prop wash, unusual external pressure, backing down, etc)
You should probably sell the hy-vent valve with every dripless stuffing kit. Up the price to cover it and avoid the issues.
Well designed tool to prevent overflow of seawater from shaft seal.
I inquired to the tech support about my vent line having water underway and I had a response almost immediately. Could not be happier with the response.
