Connector is modified by machining the cone from one end before the fitting is bored to accommodate a metallic-filament type of slip-in filter. Thus, when surface of the cone is damaged, only the cone needs replacement

Replaceable Filters and Cones for Flared-Tubing Connectors
Section of Modified Connector 
Standard connectors (types AN and MS) for flared 
tubing can be modified for incorporation of in-line 
filters and replaceable cones for seating of the flares. 
For example, the cone is machined from one end of 
an MS connector (see fig.) before the fitting is bored 
to accommodate a metallic-filament type of slip-in 
filter. A new cone is machined from a heat-treatable 
stainless steel; its shank slips into the enlarged bore, 
behind the filter which it holds in place. Thus, when 
the surface of a cone is damaged, the cone only need be 
replaced without replacement of the complete con-
nector. 
Tests have disclosed no leakage past the metal-to-
metal contacts around the replaceable cone.
