| Previously, flanged trunnions are very difficult to get. Brico's have made a few. G.W. have sent out one only, one having a 2" union used for a flange. This could be a separate piece. This material now recommended is 'Parson's white'. Is used on Jettison Karr hinge cocks and works ok, considering various metals. 320°F in Paraffin spirit. | ||
