Duotight Push-In Fitting - 8mm OD Plug

This Duotight 8mm plug is optimal for detecting gas leakage and sealing off unused junctions in tees or other connectors. Deemed suitable for both liquid and gas configurations. About Duotight Fittings - Duotight fittings are very high-quality, high-performance push-in fittings that use a double EPDM seal to ensure a solid, leak-free connection under a variety of situations. This makes it very easy to swap fittings and lines without clamps or fear of leaks. To ensure a leak-proof seal, please cut tubing as squarely as possible, using a razor or very sharp knife. We recommend the Tube Cutter w/ Duotight Removal Tool for this.
