Quick disconnect couplers are the fastest, easiest, and most reliable means of joining pneumatic and fluid transfer lines.
All quick disconnect couplers work on the same principle:
• Hardened balls or pins engage a groove in the coupler plug to hold it securely against a soft seal while permitting the assembly to swivel, thereby preventing kinking or twisting of hose.
• A sliding sleeve releases the locking balls when retracted, permitting the plug to be inserted or removed. The sleeve automatically returns to the locked position when released.
• An automatic shutoff valve in the coupler seals instantly upon uncoupling, eliminating the need for a separate shutoff.
Long Service Life. Zinc plating provides a non-corrosive finish. Heat treating hardens critical wear points. Molded Buna-n seals create a leak proof connection.
Efficient Performance. Tubular valve design provides high flow rates. Steel locking balls ensure connection holds tight under the most rugged applications. Spring loaded sliding outer sleeve allows quick connect/disconnect.
Many Sizes & Styles. Available in 1/4, 3/8, 1/2, 3/4 inch bodies with male and female pipe threads, hose barb or lock-on ends for every application.
Interchangeability. Fully interchangeable with couplers and plugs made by other manufacturers. (See interchange chart).

| WARNING: Use only on compressed air lines at a maximum pressure of 300 PSI. For safety, do not exceed the pressure limitation of the hose and/or air operated device you are using. Not for use with food or ingestible products. If this product has a hose barb, make sure hose barb size matches the inside diameter of the hose you are using. All hose barb fittings must be secured to the hose with a hose clamp or crimped-on ferrule. Failure to follow these directions exactly may result in injury and/or property damage. |
