Hooks and sliding clamps in galvanized steel, locking nut in plastic.

• Heat resistant up to 150 °C
• Lightweight, suitable for thick-walled vacuum and pressure hoses
• No need to tip the clamping slide, so no accidental slipping or opening of the hose clamp when it's closed

The plastic locking nut (229-0351 with aluminium locking nut) allows flow control or a total stop of the flow, even at already existing hose connections. The closure of the clamp can be opened in any position without screwing and unscrewing.
