Product Description

Groco Seacock Backing Block

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 curvage
  • Will not swell or absorb moisture
