OverviewIdeal Disposable Hypodermic Needles with aluminum hard hub are single-use needles designed for livestock vaccination and medication injection. The 16 gauge x 5/8" size combines a large bore with a short length — making it a preferred choice for subcutaneous (SQ) injections of highly viscous products such as oil-adjuvanted vaccines, iron dextran, and thick suspension formulations where faster flow rate is critical. The 5/8" length keeps the injection shallow and in the SQ tissue plane, reducing the risk of inadvertent intramuscular injection. 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. Single-use disposable design maintains hygiene and sharpness for every injection.Key Features 16 gauge x 5/8" — large bore, short length for fast SQ delivery of viscous products 16 gauge bore provides maximum flow rate for thick, oil-adjuvanted, and suspension formulations Short 5/8" length keeps injection in the SQ tissue plane — reduces inadvertent IM injection risk 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: 5/8" Hub Material: Aluminum (Hard) Type: Disposable Hypodermic Needle SKU: 16651106 Species: Cattle, horses, swine, sheep, goats Best For Subcutaneous (SQ) administration of oil-adjuvanted vaccines requiring fast flow rate Iron dextran and other thick suspension injections in swine and livestock Situations where a large bore is needed but injection depth must remain shallow Operations stocking a large-bore short needle for viscous SQ product delivery
