Nipples N-1 to N-4 are fabricated from Kel-F plastic, to give extra life and structural strength. They are machined to O.E.M. specification, deburred and polished to prevent bubble pattern break up.
Nipples N-5 to N-9 are moulded from high density linear polyethylene for long life and structural strength. The particular material used is chemically inert to prevent contamination.
Nipples are designed with a smooth concentric and having no flashing, to eliminate bubble pattern break up. They are also designed to prevent popping of transmission lines, and are chemically clean.
Nipples N-10 to N-21 are fabricated from stainless stell or platinum as specified.
