This Straightline Performance nitrous oxide bottle valve is a low-profile replacement valve with a built-in siphon tube, designed to fit 2.5 lb nitrous bottles with a 3/4" neck. Its compact body and side-mounted control knob make it a practical choice for motorcycles, UTVs, and custom engine bays where space is tight.

The integrated siphon tube supports consistent liquid nitrous delivery, and the valve is engineered for a high flow rate measured in grams per second to keep pace with aggressive power demands.
