RL7316 Series
Undefined product name

RFS rigid line components are available for both unpressurized (indoor) and pressurized, flanged (outdoor) systems. ;
Sizes available are 7/8", 1-5/8", 3-1/8", 4-1/2", 4-7/8", 6-1/8" and 7-3/16�.
All components are manufactured to the most exacting tolerances.
Other line sizes are available on special order.


� Line inner and outer tubing is of high conductivity, hard-drawn, copper, milled to exact dimensions. Unflanged components for indoor use are polished and sprayed with a clear lacquer to maintain a high lustre finish
� Flanges and mitred elbow joints are TIG welded for maximum strength
� Captive PTFE dielectric insulators are used exclusively in lines and elbows to ensure precision mating and stability of components after assembly
� All inner conductor connectors are silver plated
� All components conform to the relevant EIA or IEC standards
