I have a nylon part, into which a plastic part fits. The nylon part has a 4mm recess of around 10mm diameter and is a rather poor friction fit, but the joint needs to be proof against DOT 4 hydraulic fluid, under no pressure and be mechanically strong. The plastic part fits into the nylon part by around the 4mm.
I am looking for suggestions for a suitable adhesive for the job please.
I was thinking to cut grooves inside the nylon part and around the diameter of the plastic part, to help the strength.
