Wall thickness is 0.180" in black polyethylene

Elkhart Plastic tanks are manufactured to meet quality and health safety standards. With fewer impurities, these tanks are strong enough to take the bumps and bangs without compromising the security of your fresh water storage. Elkhart Plastics uses a process called roto-molding in which high-density plastic is rotated and molded into shape. This process creates a seamless tank in which the walls are of equal thickness, with no weak spots to cause trouble later. It is this process that has earned Elkhart Plastics the reputation for quality tanks. 

THE SEALED HOLE ON TOP OF THE TANK IS FROM THE MANUFACTURING PROCESS. IT IS A VENTING HOLE USED DURING THE CREATION OF THE TANK.  IT HAS NO FUNCTIONAL USE FOR THE END-USER.

PLEASE NOTE: All returns are subject to approval. 

Dimensioned Print and Gallery Views

The original 4275 part print marks the maximum dimensions as 82 7/8 inches long, 21 3/4 inches wide and 16 3/16 inches high. The height includes the deep end sump. Its top outline has end cutouts and a stepped recess; the underside slopes toward the sump rather than forming a rectangular box. The existing listing specifies a 3-inch outlet.

Only overall dimensions are called out on this print. The rendered views and rotatable model are visual reconstructions; undimensioned cutouts, sump sections, recess transitions and manufacturing marks follow drawing proportions. These views are not toleranced manufacturing CAD or a fit certification. Use the retained original blueprint and compare your existing tank, plumbing and mounts before ordering.
