When a garden hose or irrigation supply line suffers a mid-section split or cut, a solid inline coupler is the fastest repair. These 1 in brass barb union fittings restore the line with a straight equal-diameter splice, each presenting matching 1 in barbed shanks on both ends so the hose slides on securely without reducers or thread fittings. The serrated barb ridges grip the hose interior firmly, preventing blowout or pull-back under normal irrigation pressure without requiring clamps in most applications. Machined from solid brass, each coupler resists the corrosion, UV degradation, and temperature cycles that deteriorate plastic alternatives, and the material tolerates continuous service to 100 degrees C (212 degrees F) for warm-water greenhouse or process-loop use.
