High-Performance Compact Flanged Fittings with M6 and 1/4-28UNF Thread Options

What really sets these apart is how easily they let you tailor everything — custom vial sizes, labeling options, concentration levels, even bulk synthesis if your project demands it, so you're not stuck with off-the-shelf specs that almost work but don't quite fit.

They handle rigid tubing from 1.6mm up to 3.2mm outer diameter, and the M6 or 1/4-28UNF thread choices give you flexibility for different manifold setups without extra adapters, which is basically why most buyers go with teh HF6 rather than generic flanged fittings.

Temperature range hits about -27°C to 108°C, and the 1500 psi max presure means it's not great for high-flow oil lines or anything with heavy shock loads — better suited to controlled lab or medical device environments where you need consistent fluid handling.

Tool-free assembly is pretty much a time-saver in tight spaces (usually 20 seconds per connection once you've practiced), but real kicker is the PVDF, PPS, or PEEK materail options, so you pick based on chemcial exposure rather than tempearture tolerance.

50 units or so is the typical MOQ for custom colors like natural or black, though we usually have stock in natural for 1/4-28UNF — lead time on M6 and PEK versions runs about 2 to 3 weeks depending on the batch size, in my experience.
