Glass filled split poly connectors


The coupler is produced from a glass fiber reinforced nylon resin. The coupler is heat and UV stabilized, and offers excellent impact strength. It’s reusable and is ideal for temporarily
coupling conduits, particularly at slack-loop locations, and also for air-assisted jetting applications. The coupler is easily assembled using a 7/16” nut driver.
