Conex coupling for soldered and threaded connections 35 x 1" bronze (model 4270G035008000)

Conex coupling for soldered and threaded connections 35 x 1" bronze is a dual-purpose pipe connector designed for joining copper or compatible metal pipes and fittings. The component combines a solderable sleeve with a threaded end, allowing installers to create secure, mixed-method joints in plumbing and heating systems. Made of bronze, the coupling resists corrosion and provides mechanical strength suitable for potable water, hot water and general fluid installations where robust metal fittings are required.

Advantages

The bronze construction ensures good resistance to corrosion and long service life in contact with water and typical heating fluids. Combining soldering and a threaded connection in a single fitting simplifies installation when different joining methods are needed on either side of the joint. The dimensional compatibility with standard 35 mm and 1" thread connections allows straightforward integration into existing piping runs, reducing the need for adaptors. The solid metal body provides mechanical durability and reliable sealing when assembled with appropriate solder or sealing materials.

Suitable for

• Domestic and commercial potable water supply systems
• Central heating and hot water circuits
• Repair or modification of mixed-material pipework
• Plumbing applications requiring a combination of soldered and threaded joints

Key specifications

• Material: bronze
• Connection types: one solderable sleeve side and one threaded side
• Size: 35 mm (soldered side) x 1" (threaded side)
• Intended media: water, heating fluids and compatible non-corrosive liquids
• Typical applications: plumbing and heating installations

How to use

Prepare pipe ends by cleaning and deburring to ensure proper fit and solder adhesion on the solderable side and clean threads on the threaded side. Apply appropriate flux to the solder joint area and heat evenly until solder flows to form a secure bond. For the threaded side, use suitable thread sealant or PTFE tape on the male thread before tightening to the specified torque for the system. Verify alignment and allow soldered joints to cool before pressurizing. Follow local plumbing codes and manufacturer recommendations for working pressures and temperatures.

Usage recommendations

Use the coupling with compatible metals (such as copper) and approved solder and flux products. When assembling threaded connections, select a thread sealant suitable for potable water if used for drinking water systems. Inspect joints for leaks after initial pressurization and perform periodic checks as part of routine system maintenance.
