4 Inch Schedule 40 PVC Couplings

In piping terminology, coupling and coupler are often used interchangeably for a fitting that joins two pipe sections. The exact meaning can vary by supplier or application. For this category, the products are identified as PVC and CPVC fittings with socket-end connections for joining compatible ventilation ductwork or piping components. Review the product specification to confirm the intended connection.

A PVC coupling joins two compatible pipe sections and is generally used as a fixed connection. A PVC union is designed to allow the connected sections to be separated more easily for maintenance. The appropriate choice depends on system layout, access requirements, and the connection design. IPF Colasit’s listed fittings use socket-end connections; confirm the required fitting type before ordering.

For 4 inch PVC pipe, select a coupling specified for compatible 4 inch PVC and the applicable Schedule 40 dimensions. The coupling must match the pipe’s outside diameter, connection style, and material compatibility. IPF Colasit lists multiple size configurations and socket-end connections, while custom size reducers are available upon request. Verify the exact dimensions before purchase.

The exact dimensions of a 4 inch Schedule 40 PVC coupling can vary by manufacturer, fitting material, connection design, and product configuration. Confirm the outside diameter, overall length, socket depth, and wall details against the supplier’s current specification. IPF Colasit’s fittings are offered in multiple size configurations, so request the applicable dimensional information for the selected fitting.

Pricing for a 4 inch PVC coupling is not specified in the available product information. Cost may depend on the PVC or CPVC material, quantity, configuration, connection requirements, and whether a custom reducer or other variation is requested. Contact IPF Colasit with your application and quantity requirements to request current pricing and product-selection guidance.

PVC coupling sizes vary by product range and application. The available IPF Colasit fitting information identifies multiple size configurations from 4 inch to 24 inch, along with socket-end connections and custom size reducers available upon request. Select the size that matches the connected components and confirm material, dimensions, and connection compatibility before specifying the fitting.
