## Long description

BWT W+M Flex straight connector 3/8" is a plumbing fitting engineered for reliable, low-profile connections in water treatment systems. The straight 3/8" design creates a compact link between pipes, filters and appliances, suitable for installations where a direct inline coupling is required. The connector is intended for use with potable water systems and filtration units, providing a straightforward mechanical join that minimizes space and maintains a secure flow path.

The straight connector offers a compact footprint and a simple installation process that reduces the need for additional fittings. Its 3/8" straight configuration supports a stable, low-resistance flow and is compatible with common water treatment components.

How to use
Prepare the tubing or fitting ends by cutting clean, square and deburred. Insert each tube or compatible fitting into the connector until the seating position is reached, following the connector's assembly guidance.

After installation, perform a pressure check and inspect all joints for leaks under normal supply pressure before returning the system to service.
