This white plastic adjustment knob is made through precision injection molding. The outer vertical rib construction helps prevent slipping during rotation. The internal spoke reinforcement construction significantly increases its structural strength and avoids breakage from constant rotation.

The central mounting hub is designed to fit perfectly with the matching shaft so that it rotates without any idle slipping. The plastic material possesses great weather resistance properties and can be used for indoor use.

Applicable for use in replacement parts for floor heating manifolds, radiator thermostatic valves, small testing equipment, water treatment equipment, and other mechanical control knobs. We welcome OEM customization and can manufacture new molds based on your drawings/samples.
