Equiparts carries thousands of stems and cartridges for faucets and showers. Our inventory includes stems and cartridges made by Altman, Acorn, American Standard, Artistic Brass, Auburn, and more (that’s just some of the manufacturers that start with ‘A’…). If the manufacturer of the faucet and shower you need a cartridge/stem for is not listed here, give us a call or fill out our contact form for more help, including sending us an image of what you are looking for so we can identify it. If we can’t find it, no one can.
