Industrial threaded reservoir cap designed as an OEM replacement component for cooling reservoirs. Functions to form a liquid-tight pressurized seal over the fluid filling neck, isolating coolant from environmental contaminants and maintaining internal static pressure for fluid circulation.
Features
Contaminant Exclusion: Blocks ingress of airborne particulate, metal grinding dust, slag, and shop grease into deionized water loops
Pressure Containment: Maintains closed-loop system integrity for standard operating pressures without venting fluid vapor
Toolless Access: Knurled outer profile allows manual tightening and removal without auxiliary tools
Sealing: Internal recessed groove design ensures positive compression seal against reservoir neck rim
Chemical Resistance: Inert to deionized water, ethylene glycol, propylene glycol, rust inhibitors, and algaecides
Thermal Cycling Resilience: Withstands continuous cycling between storage and high-duty cycle operating temperatures
Fitment: Manufactured to original equipment dimensions for direct replacement without modification
