Brass male thread union connector for plumging system is forged from high-purity brass and is not easily broken.
Suitable for pipeline systems such as water, oil, and gas. Adopting NPT/BSP standard threads, it has strong sealing performance and is an ideal connector for engineering matching, hydraulic equipment, and fire protection pipelines.
Hexagon joint brass pipe fittings are widely used in water, oil, gas pipe system and HVAC system.
Normally the material based on 59-1 or H62, but for the water plumbing system will requrie the lead free material.
Applicable Medium:Water, air, oil, natural gas, non corrosive liquids
Material Properties:Corrosion resistance, oxidation resistance, high mechanical strength, and good processing performance

Q1: Is this brass hexagonal double joint corrosion-resistant? In which media is it suitable for use?
A:Good corrosion resistance. This product is made of HPb59-1 or H62 brass material, which has good corrosion resistance to common media such as water, air, oil, and natural gas. It is not recommended to use it in strong acid, strong alkali or seawater environments for a long time. If there is such a need, stainless steel or special coating versions can be selected.
✅ The lead-free brass version is suitable for drinking water systems and complies with RoHS environmental standards.
Q2:Can this connector be used on natural gas pipelines?Is it safe?
A:yes, but need choose the suitable brass, such as HPb 59-1 or higher.And consider the specific sealant tape and below working pressure 2.5Mpa.
Q3:Can the thread sizes at both ends be different? For example, 1/2 inch on one end and 3/4 inch on the other end?
A:Yes,This product supports customized double outer thread fittings with different thread specifications at both ends, used to connect pipelines of different diameters.Such as 1/2-3/4 etc.
