Dramm - Irrigation Assembly Fittings
Brand: Dramm
Irrigation Assembly Fittings
Three small assembly parts used when building nozzle drops and micro tubing runs on Dramm irrigation systems: a two piece white weight for a hanging nozzle drop, a 4mm x 7mm barbed connector for joining micro tube, and a swivel adaptor taking a 1 in swivel thread to 25mm insert tubing. They are build-list items rather than catalogue products. Dramm publishes a spec sheet for none of the three, and only the swivel adaptor is identifiable in Dramm's own literature.
These are unrelated parts sold together, so pick by the job rather than by comparison. The swivel adaptor is the one with a documented place in a Dramm system: it appears as a listed component in the PolyRail parts guide inside Dramm's JetFog and JetRain grower manuals, and its 25mm insert half matches Dramm's 25mm (3/4 in) PE irrigation tubing and the 25mm PolyRail extrusion, which is the higher flow, better supported of Dramm's two rail sizes. The hanging nozzle weight and the barbed connector are supplied as described - a white two piece weight and a 4mm x 7mm barb -. Dramm publishes no dimensions, materials or ratings for either, so nothing further is claimed here.

- Joining and extending micro tube runs
- Weighting a hanging nozzle drop
- Adapting 1 in swivel thread to 25mm insert tubing at the end of a line
