Alicat mass flow meters and mass flow controllers with full-scale ranges of 0-50 sccm or less ship with #10-32 UNF ports. We include stainless steel #10-32 UNF to 1/8″ NPT adapters with these instruments for greater flexibility in connecting to your process.
Note that using the #10-32 UNF to 1/8″ NPT adapter introduces additional dead volume on account of the wider tube size. For fastest flow response, use tubing sized for the #10-32 process connections. We recommend this item be hand tightened only.
