Easy-Install Slotted Washers
A slot in the side allows you to install and remove these washers without completely disassembling your joint.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Black-oxide steel washers are mildly corrosion resistant in dry environments.
Zinc-plated steel washers are corrosion resistant in wet environments.
