Conditional please try to measure the diameter of the pipe and then choose against the details of the hole diameter parameters, remember to set where to measure the outside diameter!
If you really can not accurately measure the outer diameter of the inlet pipe, you can refer to the following introduction:
1. for inlet hose without degreasing film
The outer diameter of the inlet and outlet hoses for filter drums with 12/16 mm hoses is usually 13-14 mm, choose 12 mm (e.g. CF800, Ihane 250/350).
The outer diameter of the inlet and outlet hose for filter drums with 16/22 mm hose is usually 17-18 mm, choose 16 mm (e.g. CF1200, Egham 600, Neatley filter drums).
2. Inlet hose with degreasing film
When used for de-oiled membrane inlet pipe, only the diameter of the de-oiled membrane part of the pipe is measured, it has nothing to do with what brand of filter drum is used.
The pipe diameter of the degreasing membrane part is different for different brands, so please be sure to measure the outer diameter before purchasing.
23mm is suitable for 20-21mm outside diameter
25mm is suitable for 22-23mm outside diameter.
If you feel loose after installation, you can use a hair dryer to blow the rubber ring at both ends of the protective sleeve, the fit will be better.
