Sayco valve seat

Any suggestions of getting the seat out of the body. I applied as much pressure to unscrew it as I dared without possibly stripping the square out. I sprayed "penetrating oil" on its still tight.

It will come. Repeat the pentrating oil, and let it set for as many hours as possible.

A good quality seat removal tool will not give you any concern about stripping out the square. I use a set like pictured below.

If you have the correct seat wrench and it is inserted firmly into the seat's opening, you will not strip it.
