LQ1U, High Purity Fluoropolymer Fitting, Tubing Connection, Union Reducing
SMC high purity HYPER FITTING series LQ* responds to the latest demands in process control. From parts cleaning to assembly and packaging, all processes are controlled for cleanliness, and the use of new PFA virtually eliminates particle generation and TOC (total organic carbon) allowing confident use for the most demanding applications. If chemistries or flow requirements are changed during process, our face seal design allows for quick change of tubing, and/or tube diameters, using the same fitting body. ***We are currently experiencing long lead times for fluoropolymer products. Please consult with SMC representative for accurate lead times***
- High purity fluoropolymer fitting
- Tubing connection
- Operating temperature: 0 to 200°C
- Variety of size combinations available
