BACK BLOCK 3/4″-1″ SEACOCKS

Description

Flanged seacock installation is improved with the use of a backing block between the valve flange and the hull.

• Each size fits multiple seacock sizes


• Press threaded inserts into the hull side of the backing block into the holes that match the seacock flange


• 1/2″ thickness is rigid enough for a secure installation but flexible enough to conform to minor hull curvature


• Will not swell or absorb moisture

Size: 4.29″ Dia.
Fits: 3/4″ & 1″ Seacocks
Bolt: 5/16″ – 18″
