Description and benefits
The OPTIMQ shut-off blades are a perfected solution to replace the usual spatulas when making under-pressure connections.
The blades are used to cut the water flow during the pipe drilling process and the installation of the connection or branch.
After drilling the pipe and raising the hole cutter, the blade is introduced to isolate the upper part of the saddle from the network pressure and thus be able to remove the drilling device. Once the connection has been installed, the blade is removed to finish the installation. During the inserting and extraction of the blade there is an imperceptible water leak through the slot of the saddle thanks to the double-seal system inside the saddle.

There are 4 blade sizes that cover all OPTIMQ saddle and under-pressure connector sizes:
- 1” for ¾”, 1” and PE32 saddles.
- 2” for 1¼”, 1 ½”, 2” and PE50 saddles.
- DN65/80 for DN65, DN80 and PE90 saddles and connectors.
- DN100 for DN100 and PE110 connectors.
For sizes DN65/80 and DN100 the same shut-off arm can be used by exchanging the blades, unscrewing the fastening screws of the blade.
The making of under-pressure connections with saddles or connectors using shut-off systems with rotary blades makes the work easier, minimising efforts and reducing the time needed for the intervention. We recommend applying a small amount of grease to the shut-off blade before inserting it in the saddle.
The shut-off blades consist of a tempered stainless steel blade and a nickel-plated steel arm. The OPTIMQ shut-off blades are inserted in the saddle with a small turn, which reduces significantly the effort required. The shut-off blades can be handled manually or with the combination or ratchet wrench, as the arms of the blades have the necessary dimensions to fit with both types of wrenches.
