Diversitech 1839022 Hydraulic Expander Head 1-1/8 in

Product Description

The DIVERSITECH 1839022 is a replacement hydraulic expander head sized for 1-1/8 inch tube diameter work. It is designed for use with hydraulic tube expander tool systems and accepts soft copper, steel, aluminum, and brass tubing. HVAC technicians and refrigeration service pros use expander heads like this one to flare and expand refrigerant line ends to the correct diameter before brazing or fitting connections. This single-head replacement keeps a hydraulic expander kit operational without replacing the full tool, making it a practical shelf spare for active service vans and shop benches.

This expander head is suited for both ducted and ductless system applications, covering the range of tube expansion tasks that come up in residential and light commercial HVAC and refrigeration work. The 1-1/8 inch size is common in larger-diameter refrigerant line sets and system piping where a precise, consistent bell or expanded end is required before making a mechanical or brazed joint.

Key Features

• Sized for 1-1/8 inch tube diameter expansion
• Compatible with soft copper, steel, aluminum, and brass tubing materials
• Hydraulic tool type for consistent, controlled tube expansion
• Single replacement head — integrates with existing hydraulic expander kits

Compatibility

Designed as a replacement expander head for hydraulic tube expander tool systems accepting a 1-1/8 inch head size. Verify drive and receiver dimensions against your existing tool kit before installation.

Installation Notes

Expander head installation and tube expansion work is typically performed by licensed HVAC technicians or refrigeration mechanics. Always recover and isolate refrigerant from any system before working on refrigerant lines, in compliance with EPA Section 608 regulations. Ensure the replacement head is fully seated and locked into the hydraulic driver body before applying pressure. Inspect the expanded tube end for uniformity and absence of cracks before completing any brazed or mechanical connection.
