Ordering Speedseal
This replacement cover is made of 1/4" traditional naval brass 112 with a high specification nitrile O-ring in a machined channel.
The O-ring seals onto the pump flange inside the circle of bolt holes giving a perfect engineering seal without the use of gaskets or sealant.
Two slots in the cover allow simple location or removal even if you can't see what you are doing. The bolts are high grade marine stainless steel 316.
As the bolts are outside the seal, the screw holes not being used can be ignored. Six and four bolt casings take four bolt Speedseals and three bolt casings use three bolt Speedseals.


The area over the impeller has a machined recess equal to the thickness of the gasket originally used. This guarantees the correct space for impeller rotation.
