4″4040 Interconnector Coupling

Description

4040 Interconnector is a high-strength plastic coupling designed to link 4-inch Reverse Osmosis membranes in series. This “Product Water Bridge” ensures that the permeate (pure water) from one membrane flows seamlessly into the next without being contaminated by the high-pressure brine (waste water) surrounding it.

Uses & Applications:

• Standard 4″ Housings: Fits all stainless steel and FRP 4040 pressure vessels.

• Multi-Membrane Arrays: Required for systems with 2 or more membranes per housing.

• Standard Compatibility: Works with Toray, DuPont/FilmTec, and Vontron 4040 membranes.

Benefits:

• Rigid Construction: Made from food-grade ABS to resist cracking under pressure surges.

• Dual-Ring Groove: Features precision-machined grooves for $3.5$ mm O-rings (AS568-210).

• High Chemical Resistance: Built to withstand aggressive acid/alkaline cleaning cycles (CIP).

Technical Specs:

• Outer Diameter: ~19.0 mm (Permeate tube fit)

• Length: ~100–120 mm (Standard Industrial)

• Seal Type: Double Radial O-Ring (Requires 4x $3.5$ mm rings)
