PrimoChill's Single Barb Fittings Features and Clamp Dynamics
The threads are molded in precision-ground cavities resulting in perfectly
matched threads at the parting line. This produces the cleanest, most accurate
molded thread possible.
Why PrimoChill's fittings are better
Our single-barbed fittings are designed so the mold parting line stops at the
base of the barb. The ridge and the barb's conical surface are free of the
molded-in leak path present in multiple barb fittings. The conical surface is
glass-like and smooth allowing excellent sealing.
The straight barb shaft provides space for the hose to relax behind the barb
causing the clamp to work like a drawstring. This forces the hose diameter to
become smaller than the flare of the fitting's barb. If the tubing swells from
internal pressure (near burst), the clamp will be pulled up tight to the back of
the barb and a tight seal will be maintained.
Clamp placement on a single barb fitting.
Clamp positioning in the recess behind the barb allows for tubing compression
anterior to the barb and results in a secure seal with without excessive clamp
Clamp placement on a Multiple barb fitting.
Clamp can only be placed over barb. In general, much more clamp pressure is
required to secure a seal than that necessary with a single barb fitting.
Why multiple barb fittings fail
Mismatches often occur with poor quality or worn tooling, causing misaligned
threads and barbs that result in leakage. With multiple barb fitting designs, it
is virtually impossible to avoid creating parting lines on the barb surface.
These parting lines create leak paths which become more pronounced as the mold
