Emjay® Grommet Fittings are used to tee off a PVC mainline with a drip or micro irrigation polypipe. Emjay® Grommet Fittings are made to precisely fit the Emjay® Grommet and form a perfect seal every time. Although a standard connector can be and often, is used, we do recommend that this specially designed fitting is used with all Emjay® Grommets. The Emjay® Grommet Fitting comes pre-assembled from the factory with the fitting and the grommet. As with all other Emjay insert fittings this fitting utilises the unique (and registered) Emjay® barb configuration to ensure that once connected the fitting stays in.
