How to chose right size PP connector?

For our connector, translucency is made of PP material, white is made of PE material, and full transparency is made of acrylic material, all of which are food grade. 

Thermal performance: capable of disinfection and sterilization at temperatures above 120 ℃, without deformation at 150 ℃ under no external force. Embrittlement occurs below -20 ℃.

Chemical stability: Resistant to most organic solvents such as acid, alkali, salt, alcohol, phenol, aldehyde, ketone, etc.

Product use: non-toxic and odorless, heat-resistant, suitable for direct connection of hoses, convenient and fast.

Scope of use: Biochemical analysis, water quality analysis, cell culture, environmental testing, inkjet printing for ink supply, thermal engineering, pressure calibration, pressure measurement, Refrigeration, disinfection, teaching, scientific research experiments, dental diagnostic and treatment equipment, and many other general fields. Especially in some precision scientific instruments and equipment. The low-pressure gas-liquid fluid system inside has been widely used.

Appearance: The surface is smooth without burrs, burrs, obvious deformation, and the color is normal without yellowing or blackening.

Our size all refer to the minimum outer diameter of the joint edge, because hoses have elasticity, the diameter at the clamp of the pagoda joint will be greater than the diameter at its edge. If your hose inner diameter is not included, an approximate value can be taken normally for connection. If your hose inner diameter is 6mm and the elasticity is moderate, then buy a 6mm connector. If your hose inner diameter is 6mm but the elasticity is small, buy a 5mm connector.
