Used in
Common applications for DSZHSplit-system air-conditioner service: DSZH manifold bases and SAE/NPT reducers integrate with technician gauge sets for pressure monitoring and refrigerant charge.
Rooftop packaged unit maintenance: Flare connector caps, hose tips, and union fittings expedite field replacement of damaged lines and adapters on commercial cooling systems.
Refrigerant recovery and recycling: DSZH bottle adapters (R600A-rated) connect recovery cylinders to hose lines, enabling safe extraction of flammable and standard refrigerants.
Process-cooling loop installation: SAE straight male/female unions and reducers support temporary or permanent manifold assembly on industrial water-chilled equipment.
Heat-pump seasonal service: DSZH dudgeon extensions and adapter kits allow technicians to connect diagnostic gauges to restricted or recessed access ports on reversing-valve manifolds.
Field emergency repairs: Individual DSZH fittings stocked in stock allow technicians to repair or modify hose connections on-site without returning to the shop for components.
