    Self-closing push-in couplings

    This category is dedicated to special couplings that close after disconnecting the hose thanks to a check valve. Self-closing clutches are used mainly in automotive air conditioning. We offer straight variants with several types of threads, L-clutch swivels and scotch clutches.
