What is a CBM brass ball joint AP 3/8"M - 3/8"F used for?

CBM brass ball joints are directional water connectors used in water heater installations, boiler systems, and industrial heating circuits across Southeast Asia. The 3/8" male-to-female design allows flexible pipe routing in confined spaces while maintaining pressure integrity in hot-water applications up to typical system temperatures.

What are the specifications of the CBM AP 3/8" brass ball joint?

The CBM AP model features 3/8" NPT male and female connections, brass body construction for corrosion resistance, and rated operation in water heater and thermal systems. It complies with CE and EN 60730 standards for heating equipment components and supports flexible installation angles in residential and commercial heating circuits.

Where can I buy CBM brass ball joints in Singapore?

3G Electric stocks CBM brass ball joints (SKU 10013) at our Woodlands distribution centre in Singapore. We offer same-day dispatch for in-stock items and next-day delivery across the island. Contact our technical team for bulk pricing on water heater spare parts and SE Asia logistics.

How do I install a brass ball joint in a water heater circuit?

Turn off and depressurize the system before removal. Use two wrenches to disconnect the old fitting—one on the body, one on the connection nut. Apply thread sealant tape (PTFE) to the male 3/8" thread, install the ball joint hand-tight, then tighten with wrenches. Pressure-test before restoring heat. Follow local plumbing codes for your installation.
