Flame-Retardancy FR Quick-Connect Fitting KR-W2 Series Bulkhead Union KRE-W2
Caution
- *See the catalog for detailed specs and materials.
- Product images may be representative images. Refer to the catalog for details.
Product Description
A flame retardant (UL-94 standard V-0 equivalent) one-touch fitting.
[Features]
· Supports FR soft nylon.
· The chuck engages the work piece securely, while collet maximizes the retention force.
· Its special shape ensures a secure seal and minimal resistance when inserting a tube. Can be used in everything from low vacuums to 1 MPa.
· Effective for piping in tight spaces.
· The body and threaded section can be rotated enough to allow for positioning.
[Applications]
· Can be used for relay (through-panel) connection of tubes for panel mounting, etc.
