Product Description

The DSZH tube expander with clutch (COR35106) is an HVAC tool designed for expanding soft copper, aluminum, and other soft tubes across six standard sizes from 1/4" to 3/4" OD (6–19 mm metric). The clutch mechanism engages the eccentric cone during expansion and disengages automatically at completion, minimizing operator effort. Lubrication with motor oil at the drive rod, handle, bearing connected to cylinder head, and screws is required for sustained operation. The unit ships with carrying case CT-207. 3G Electric supplies this tool for HVAC applications across Singapore and Southeast Asia with full DDP delivery.

Common applications for DSZH

Split-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.
