Description
The PT Coupling STA-LOK® VSL-Dust Cap is a coupler dust cap cam and groove cap that closes off an open adapter. STA-LOK® is PT Coupling’s positive locking feature: a carbon steel or stainless steel hitch pin clip (or a padlock) keeps the cam arms from opening under vibration, pulsing, wear or when handling hazardous materials, helping prevent spills.
