Brass Hose Barb for Pneumatic Lines
The ZORO SELECT 6AFL2 is a straight brass fitting that joins a 5/8 in hose to a 3/4 in male NPT thread. It is intended for low pressure pneumatic and water circuits where a rigid, corrosion resistant connection is required. Installers needing a simple barbed transition without elbows or reducers will find the straight profile convenient. The hex head measures 1 1/16 in for standard wrench engagement.
Thermal Noise and Power Characteristics
As a passive brass component the fitting generates no heat, draws no power and produces no audible noise during operation. System temperature and sound levels depend entirely on the compressor or pump feeding the line. Brass construction resists galvanic corrosion better than plain steel in mixed metal plumbing. No electrical supply or cooling consideration applies to the fitting itself.
Accessory and Compatibility Notes
The package supplies the single barbed fitting only; no hose clamps, thread sealant or additional adapters are included. Users must provide a compatible 5/8 in inner diameter hose and apply appropriate thread sealant on the NPT side to ensure a leak free joint. California Proposition 65 warnings indicate the brass contains chemicals known to cause cancer and reproductive harm. Buyers needing a different barb size, elbow geometry or stainless material must select another part.

Questions about this item
How do I install the 5/8 in hose barb with 3/4 in MNPT without stripping the threads?
Wrap PTFE tape clockwise on the NPT threads, thread the fitting by hand until snug, then tighten with a 1 1/16 in wrench one to two turns; over-tightening brass NPT threads is the common mistake that causes leaks.
What maintenance will the brass hose barb need over time?
Inspect the barb and NPT threads annually for corrosion or mineral build-up; clean with a brass brush and re-apply thread sealant if seepage appears, otherwise the fitting requires no scheduled replacement.
What is the first limit reached under sustained pressure?
The brass material and NPT thread seal determine the pressure ceiling; sustained pressure beyond the fitting's low-pressure design rating will cause thread deformation or barb leakage before any other failure mode.
