A4LC-BL to a clip that blocks the quick coupling mechanism used in water treatment systems. When slid under the coupling mechanism, it increases the safety of the connection and reduces the risk of accidental disconnection of the hose. Made of plastic. Fits quick couplings for hoses 1/4 inch.
A4LC-BL clip locking mechanism for quick couplings is a practical securing element for connections in water treatment installations. The clip, inserted under the quick coupling mechanism, increases connection reliability, reduces the risk of accidental hose disconnection, and helps maintain stable system operation. It fits quick couplings designed for a 1/4 inch tube, so it works well in many solutions such as a water filter, reverse osmosis filter, reverse osmosis system, or other water filtration systems.

A4LC-BL is a small but very important securing element for quick couplings used in water systems. Its task is to lock the coupling mechanism after the tube has been properly seated, making the connection more resistant to accidental disconnection during everyday use.
This solution is especially useful wherever safety and stable system operation matter, for example in home filtration systems, under-sink sets, and systems such as reverse osmosis or an advanced water filtration system.
The A4LC-BL clip is used in installations where quick couplings are employed to connect tubing. It can be used in many popular solutions based on 1/4 inch tubes, including water treatment installations and systems such as an osmotic filter, reverse osmosis filter, or a classic water filter.
It is an accessory that increases connection security in places particularly exposed to accidental movement of tubes, service work, or everyday use of the device.
After the tube has been properly inserted into the quick coupling, the clip should be slid under the coupling mechanism. This type of installation makes it harder for the locking element in the quick coupling to be released accidentally and improves connection security. It is a simple solution that supports the reliability of the entire system.
The clip is intended for quick couplings for 1/4 inch tubing. Before use, make sure the tube has been properly inserted into the fitting, as the lock serves to secure an already correctly made connection.
The lock is made of plastic. This material ensures low weight, ease of use, and practical application in typical water systems equipped with 1/4 inch quick couplings.
Thanks to its universal fit for the 1/4 inch size, the clip can be used with all quick couplings designed for this type of tube.

The clip is used to lock the quick coupling mechanism. After being slid under the mechanism, it increases connection security and reduces the risk of accidental tube disconnection.
The clip fits all quick couplings designed for 1/4 inch tubing.
Yes, the clip can be used in reverse osmosis systems and in other water treatment and filtration installations that use 1/4 inch quick couplings.
The product is made of plastic.
After properly inserting the tube into the quick coupling, slide the clip under the coupling mechanism. This makes the connection better protected against accidental release.
No, the clip does not perform a sealing function. Its task is to mechanically secure the quick coupling against accidental disconnection.
The product is suitable for water treatment systems, installations with water filters, osmosis systems, and other filtration systems using 1/4 inch tubing.
It is a simple way to increase installation safety. The clip stabilizes the quick coupling mechanism and helps reduce the risk of accidental tube pull-out during use or system servicing.
