Kynar Ozone Fittings

Kynar (PVDF) is used where other materials are less resistant to ozone, so the fitting does not degrade in an ozone gas line.

The supplier does not publish the thread standard — tell us what your existing fitting is and we will confirm the match before you order.

1/4″ tubing, commonly PTFE (Teflon). The fitting compresses onto the tube, so no solvent cement is needed.

64174 is barbed for 1/4″ line and 64175 for 3/8″ line — both have Kynar bodies with Viton seals.

CKV22 sits in the gas line to stop water backing up towards the ozone generator.

To choose your fitting: match the tube size on your ozone line — 1/4″ for the compression fittings, 1/4″ or 3/8″ for the barbed check valves — then the connection you are joining to, whether that is 1/8″ or 1/4″ male thread, 1/4″ female thread, or a barb. Tell us the thread standard on your existing fitting and we will confirm the match.
