In 2023, at rmmcia, we have begun the manufacturing a new brass fitting, patented, designed to solve a common issue when making quick and easy branch connection in polyethylene pipes without interrupting the water supply.
It consists on threaded male-male BSPP ½” fitting, featuring a hexagonal flange for tightening and a sharp-edged and oblique extension (“beak”). This end allows perforating the pipe while threading it.
The main purpose of this new connector is to allow an under pressure branching, without the need to cut off the supply or depressurize it. It doesn't require any special tools, only an adjustable wrench and Teflon tape, besides a tee clamp saddle and a stopcock.
Its inventor is Germán Sánchez Martín, and the connector has been recognized as one of the top 10 inventions of 2022 (Los 10 mejores inventos españoles patentados en 2022, Source: El Periódico).
NECESSARY TOOLS (for installation of a 1/2" drilling connector)
- Tee clamp saddle with exit (in brass or in polypropylene)
- Adjustable wrench
- Stopcock
- Teflon tape
WHAT TYPES OF PIPES IS APPLYCABLE TO?
Below you can find a chart indicating the type of polyethylene material (PE), pipe diameters and their nominal pressure (PN).
If you need to know, the tube size is overprinted on the tube itself.
ASSEMBLY PROCEDURE
(later on info about how to check compatibility with other tee clamp saddles than rmmcia's)
1- Clean the pipe surface.
2- Instal the tee clamp saddle at the chosen point.
3- Apply Teflon tape to both threads, approximately 15 turns, always in the direction of the thread.
4– Screw the flat part of the connector to one side of the stopcock ½”, making sure to leave it closed.
5- Attach the assembly to the tee clamp saddle, inserting it from the beak side.
6- Screw it until it reaches the hexagonal flange, completing the pipe perforation.
7- Carefully open the stopcock to collect the resulting cut piece -if this is the case-, and then close the stopcock again.
CHECKING THE COMPATIBILITY OF ANY TEE CLAMP SADDLE WITH RMMCIA DRILLING CONNECTOR
If an rmmcia tee clamp saddle is not used, there is a simple method to check the compatibility of others with the rmmcia drilling connector.
1) Screw the drilling connector until it reaches the end of the collar thread. Teflon tape is not necessary for the checking.
2) The beak of the connector will appear through the inside of the collar. The gasket must be installed for the checking. Mark the base of the beak at the gasket level using a marker, aligning this one in the same pipe's direction.
3) Measure (in mm) the distance between the mark and the longest end of the connector's beak. If the mark is located on a different side of that beak, extend the mark to make the measurement at the specified point.
4) Once you have that measurement in mm (A), check the compatibility table for the obtained measurement. The tee clamp saddle will be compatible with the drilling connector if the measurement obtained is equal to or greater than the one indicated in the table. The absence of a value (-) indicates incompatibility or unavailable tube.
