On/off valves control individual fluid lines Robust threaded ports accept 1/4"-28 UNF(M) fittings Anti-twist design Caps 21942-82 and -83 are designed to fit plastic bottles These Q-series solvent caps ensure a leak-free, vapor-tight seal to protect lab staff from exposure to toxic fumes, prevent ingress of particulates, and prevent evaporation of solvent. Use the on/off valves to control the flow of each line independently. The anti-twist design lets the PTFE body spin freely within the cap. No need to disconnect the fluid lines before unscrewing the cap—no more twisted tubes when the cap is fitted or removed. Easily connect semi-rigid tubing to caps using 1/4"-28 UNF(M) fittings. Connect flexible tubing using Dibafit™ PEEK™ thread-to-barb adapters. Each port features a stainless steel thread insert to enable repeated connect/disconnect. All caps are autoclavable. A 12-1/4” (31 cm) long, 1/8" OD PTFE tubing is supplied fitted inside the cap and extending into the bottle.
