The B134 carries 22 gallons in a blank of 84 lb, and that pairing tells you its intent before any spec sheet does: this is the heavy-service build of a mid-size marine water tank, nearly four pounds of wall per gallon of capacity. It goes into the boats where tankage is infrastructure - hulls that run hard, sit deep, and cannot haul out because a water tank split.
In fresh service it is FDA-compliant potable polyethylene, seamless end to end; specify waste fittings instead and the same blank becomes a holding tank with the same overbuilt wall. The water adds about 183 lb at 8.34 lb per gallon, so plan the bay for the combined load and give the base continuous support.
Ronco has rotomolded in Tustin, California since 1974 and installs all fittings per order: print the drawing below and mark your spin-weld or threaded fitting locations, or click them into the on-page fitting planner. Heavy blanks deserve early freight math - check your ZIP on the freight cost estimator. Lighter 22-gallon shapes are in boat tanks; the full family is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
