OverviewIdeal Disposable Hypodermic Needles with aluminum hard hub are single-use needles designed for livestock vaccination and medication injection. The 16 gauge x 3/4" size offers a large bore with a short-to-mid length — well-suited for subcutaneous (SQ) injections of viscous products in cattle, horses, and swine where a slightly deeper SQ penetration than the 5/8" is preferred. The 16 gauge bore delivers maximum flow rate for thick, oil-adjuvanted vaccines, iron dextran, and heavy suspension formulations, while the 3/4" length provides a bit more reach into the SQ tissue plane without risking inadvertent intramuscular injection in most livestock. The hard aluminum hub provides a rigid, secure connection to standard luer-lock and luer-slip syringes, and the sharp bevel ensures clean penetration with minimal tissue trauma.Key Features 16 gauge x 3/4" — large bore with short-to-mid length for SQ delivery of viscous products 16 gauge bore provides maximum flow rate for thick, oil-adjuvanted, and suspension formulations 3/4" length offers slightly deeper SQ reach than 5/8" while remaining in the subcutaneous plane Hard aluminum hub for a rigid, secure connection to luer-lock and luer-slip syringes Sharp bevel for clean, consistent penetration and minimal tissue trauma Single-use disposable design maintains sharpness and hygiene for every injection Compatible with standard veterinary syringes and automatic vaccinators Specifications Brand: Ideal Gauge: 16 ga Length: 3/4" Hub Material: Aluminum (Hard) Type: Disposable Hypodermic Needle SKU: 11136416 Barcode: 0993550204069 Species: Cattle, horses, swine, sheep, goats Best For Subcutaneous (SQ) administration of oil-adjuvanted vaccines and viscous formulations in cattle and horses Iron dextran and thick suspension injections requiring maximum bore flow rate Operations preferring a slightly deeper SQ reach than the 5/8" while maintaining subcutaneous placement Processing days requiring fast, efficient delivery of viscous products across large numbers of animals
