Flange-Mount Ball Transfers

Stainless steel balls offer the most corrosion resistance. They don’t need to be lubricated. Nylon balls are nonmarking.
Capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the capacity stated.

Floats for Threaded Rods

Connect these floats to threaded float rods (not included). Use them to replace an existing float or combine with rods and float valve bodies (not included) to build a float valve.
Polypropylene floats are lightweight and meet NSF/ANSI 61 standards for safe use with drinking water.
Cylindrical and rectangular floats are all self-tapping except those with a 4” diameter, which have a threaded hose connection.
