Understanding the 3 1/2 Inch Split Flange

The 3 1/2 inch split flange is a mechanical coupling designed to join pipes or fittings with flanged ends. Unlike traditional flanges that require disassembling the piping system for installation, split flanges feature a two-piece design that allows for easy retrofitting and repairs without disrupting the entire system.


1. Easy Installation:The split design of the flange simplifies installation, eliminating the need to dismantle the entire piping system.

2. Leak-Free Performance:Designed to provide a secure and tight seal, the 3 1/2 inch split flange ensures leak-free performance, even under high-pressure conditions.

3. Cost-Effectiveness:The ease of installation and maintenance of the 3 1/2 inch split flange translates to cost savings over the lifespan of the piping system.
