Strainer Fits Inside Flared-Tube Fittings
Tube Fitting 
(Male Union) 
Collar 
The problem: To provide a simple, easily replace-
able strainer that can be readily installed in standard 
flared-tube fittings. 
The solution: A cylindrical wire-mesh strainer, with 
a collar that seats on the tapered shoulder of the male 
fitting. 
How it's done: The strainer is inserted into the bore 
of the tube fitting so that the collar seats on the 
tapered shoulder at the upstream end of the fitting. 
When the coupling nut is tightened, the strainer is held 
firmly in place and a leakproof seal is formed at the 
junction surfaces. 
Notes: 
I. This strainer can be readily installed in existing 
plumbing systems that use flared-tube fittings.
