Frequently Asked Questions

What is a DSZH straight reduced double dudgeon union used for?

A DSZH straight reduced double dudgeon union is used in HVAC and refrigeration systems to connect copper pipes of different diameters, specifically from 1/4" to 5/8". It provides a leak-free mechanical joint for service, repair, or installation of split-type air conditioners and heat pumps.

What are the specifications of the DSZH straight reduced double dudgeon union?

The DSZH straight reduced double dudgeon union connects 1/4" to 5/8" copper tubing. It is a reduced fitting, meaning it joins two different pipe sizes. The double dudgeon design ensures a secure, flare-type connection without soldering. Exact pressure and temperature ratings are not specified by the manufacturer.

Where to buy DSZH straight reduced double dudgeon unions in Singapore?

You can source DSZH straight reduced double dudgeon unions through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this HVAC fitting.

How to install a DSZH double dudgeon union?

To install a DSZH double dudgeon union, first cut and deburr the copper tubing. Slide the union nut and dudgeon ring onto each pipe end. Insert the pipe into the union body and tighten the nut with two wrenches—one on the body, one on the nut. Do not overtighten to avoid damaging the flare seat.
