Manufactured by Colder Products Company of the USA, the Chemquik CQN08 series are made of ultrapure virgin PTFE with Chemraz seals for chemical compatibility.

Manufactured in a controlled environment and double bagged in class 100 anti-static clean room bags, they use no contaminating lubricants, and meet industries ultra-pure standards, making them ideally suited for most wet process chemicals found in semiconductor, pharmaceutical and laboratory applications.

The CQN08 features a patented nonspill design providing instant flow shutoff for safe line disconnections.

The metal-free spring-free flow path allows smooth, unrestricted, low turbulence flow with an industry leading Cv range of 7.3 for the double-sided shut off version to 9.4 for the single-sided shut-off, yielding a capacity of over 40g/min (water).

Designed to operate within a pressure range of 0-80lb/in2 and a fluid temperature range of -18 to +65C, the couplings are available in panel mount and in-line configurations.

Integral 0.75in NPT threads and 0.75 and 1in flare-style terminations connect to PFA, FEP and other semirigid tubing.
