Hull Curvature Mounting Pads for Flanged Seacocks
Flanged Seacock Backing Block - for 1-1/4", 1-1/2" Seacocks (5.38" Dia.)
SKU: 440493 Item ID: GRO BB-2
- For Superior Seacock Installs
Description
Groco's Flanged Seacocks installation is improved with the use of a backing block between the valve flange and the hull.
The pliancy of the material used in the block helps mate and seal the flat surface of the bottom of the seacock base to hull surfaces with a minor curvature.
• Each size of backing block fits two seacock sizes (except the 5" block)
• 1/2" thickness is rigid enough for a secure installation, but flexible enough to conform to minor hull curves
• Will not swell or absorb moisture
• Threaded bronze inserts match seacock hole pattern, leaving three additional holes for mounting the block
• Blocks for 3", 4" and 5" seacocks are available by special order; please call 800-426-6930
