Quick-Release Hose This quick-release hose features a steel interlocking alignment flange that helps prevent the connection pins from shearing off when tightening the handle to the hose or the hose to the bulkhead connector. This quick-release hose is used in Polyvance’s 8000 series, 8200 series, and 8300 series nitrogen plastic welders. Please note: If you purchased an 8000 series or 8200 series nitrogen plastic welder built before September 2020 and need a hose, you will need to upgrade to this improved design.This new hose is not compatible with welders built before September 2020, and we no longer have hoses available for those welders. To upgrade your welder, you will need to order the Quick-Release Hose Retrofit Kit. How Can I Tell if I Need to Upgrade? To determine if you need the retrofit kit, first unscrew the metal collar at the base of your handle. Next, remove the handle from the hose and look at the connector. If the connector is the old style without the metal interlock, you must upgrade to the new style. If you have a new style connector with the metal interlock, you do not need the retrofit kit.
