UPVC Coupler
The UPVC coupler manufacturer company in India. It is one of the most basic (and affordable) UPVC fittings. They are a tiny part that permanently joins or “couples” one part to another. They can connect pipe to pipe as well as pipe to the fitting. Some even diminish in size, allowing you to connect a small pipe to a large pipe or vice versa.
The UPVC coupler Manufacturer, this is the best quality product with either slip or female-threaded ends, depending on your needs. The most suitable technique to repair a ruptured pipe or leak is with slip couplings. A slip fitting replaces two couplings and additional pipe. Only one tip end of the coupling has a stop, allowing the other end to slide over a pipe’s end freely.
To complete the connection, put the PVC Slip Coupling onto the pipe and, using a PVC Disconnect Clip & Depth Gauge, slip the fitting back onto the other end of the pipe.

- Diversity: Various structural forms of pre-embedded upvc connector couplers can be selected according to specific connection requirements and environmental conditions. Common structural forms include bolted connections, welded connections, and riveted connections.
- High precision: As pre-embedded parts usually need to be placed in advance during the pouring of the structure, the pre-embedded upvc coupler needs to be highly precise to ensure the accuracy and reliability of the connection.
- High strength: The pre embedded u[pvc coupler needs to withstand the weight from the structure itself and external loads, so it needs to have sufficiently high strength to ensure the firmness of the connection.

Benefits of Using UPVC Coupler
Ease of use
The upvc coupler system is very easy to use, one end of the rebar is fixed and another end of the rebar can be rotated and threaded. That’s why it becomes very easy to use and application becomes very simple.
Reduces reinforcement used in the connection of rebar
Conventional lapping needs an extra length of rebar steel to lap the rebar. Generally for vertical lapping length of lap is considered in between 45d to 55d & for the horizontal connection, it is considered as 55d to 65d where “d” stands for the diameter of the connection bar. This extra length of the bar can be reduced by using upvc couplers.
Quick to install
Conventional lapping needs much more time as it needs to bend the bar according to the diameter and then it has to connect with binding wire or with welding method. This time can be saved bu using a coupler as it just needs to fix the bar with threads.
Higher tensile strength than convention lapping
As steel perfectly connected in upvc coupler it gives higher tensile strength than the lap splicing. The conventional rebar method gives a slicing effect in rebar hence reduces tensile strength.
Provides continuity and structural integrity
Upvc couplers achieve an ideal balance of steel and concrete by eliminating unnecessary rebar while providing greater structural integrity.
Removes hidden costs
Hidden costs like labor requirements to bend the bar and connecting the bar, extra binding material like wire or welding can be reduced in the use of upvc couplers.
