Product Description

Frequently Asked Questions

What is the CBM 1/2" quick coupling 45° pressure fitting used for?

The CBM 1/2" quick coupling 45° pressure fitting is used in refrigerant systems for HVAC and industrial cooling applications. It provides a compact, angled connection for HCFC and HFC refrigerants, rated to 45 bars maximum pressure and operating from -40°C to +120°C.

What are the specifications of the CBM 3G-CBM-05689 quick coupling?

The CBM 3G-CBM-05689 is a 1/2" quick coupling with a 45° angle, made of bronze. It has a maximum pressure rating of 45 bars, supports HCFC and HFC refrigerants, and operates within a temperature range of -40°C to +120°C. It is designed for push-to-connect installation with a double-seal leak-proof system.

Where to buy CBM quick couplings in Singapore?

You can source CBM quick couplings, including the 3G-CBM-05689 1/2" 45° model, through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on this and other CBM fittings.

How to install a CBM quick coupling 45° fitting?

To install a CBM quick coupling, cut the tube cleanly, deburr the end, and mark the insertion depth. Push the tube firmly into the coupling until it stops. To disconnect, press the clip and pull the tube out. Ensure the tube and coupling are clean and free of marks before assembly.

Common applications for CBM

Industrial boilers — CBM circulation pumps (mod. CM 30W) and solenoid valves (ELV series) for heating-loop control and pump staging.

Burner systems — CBM oil nozzles (FLU atomizer types), electrodes (ELC 200 mm), and solenoid coils (ELV 230V AC) for combustion ignition and flame supervision.

Plant maintenance and retrofit — CBM cable glands (CLI M25), motor couplings (ACC type D), and small-radius fittings (RAC 90°) for equipment reconfiguration and sensor integration.

Boiler water treatment — CBM chlorine test kits (DET free+combined) for feedwater and circulating-water quality monitoring in closed-loop systems.

Pump and motor assembly — CBM couplings, fittings, and cable glands for assembly and rewinding of industrial motors, circulation pumps, and auxiliary equipment.
