Expanding Rubber Adapter Kits


CasterHQ offers a wide variety of expandable rubber adapter kits for sale. All of these kits are easily adaptable for all casters that currently have an existing expanding rubber stem. Whether you need to replace a specific size or upgrade to a larger diameter adapter or smaller adapter, we have all industry-standard expanding rubber adapter kits in stock. Expanding rubber adapter kits consist of four parts, the first being a base washer, then a plastic spacer, the adapter itself, and finally, the neural nut that screws on top of the attaching stem of the caster to secure all of the parts. The neural nut works in two ways, it attaches the expanding adapter parts onto the stem, and at the same time, the further the neural nut is tightened, the more the rubber adapter expands for a better fitment into your tubing. Expandable Rubber Adapters range from 3/4" up to 1-3/4" in diameters to fit just about any tubing, cart, or equipment on the market.
