For dry-cleaning equipment, verify against the actual machine, valve panel, boiler or water-treatment system, gauge assembly, filtration system, utility line, pneumatic circuit, refrigeration service port, or service hose before ordering. If the product is being used outside dry cleaning, confirm compatibility with the application and operating conditions before installation.
Installation & Ordering Verification
Compare the product photo, installed component, size, connection style, and service location before ordering.
Confirm pressure, flow, temperature, material, chemical exposure, media compatibility, clearance, and mounting for the actual system.
Use qualified service personnel when installing pressure, steam, refrigeration, water, electrical, pneumatic, or equipment-control components.
Send photos of the installed part, machine tag, and service location if fitment is uncertain.
