Quick Connect Couplings
Quick connect couplings are used to seal common-size tubing to vacuum manifolds or chambers. They are ideal for frequently changed vacuum components or for sealing a glass tube to a metal vacuum chamber, as in glass ion gauges.
Quick Connect Couplings Feature:
- No tools required for inserting / removing tubes.
- Couplings are sized by the O.D. of the tube they seal.
- Material - 304 stainless steel body with 303 stainless steel nut.
- Available in either "thin wall" or "thick wall" construction.
- Couplings come standard with Buna-N O-rings. Fluorocarbon replacements are available in the Ordering Table below.
