6an ORB Bottle Nipple Fitting

The 6AN ORB Bottle Nipple Fitting from NITROUS EXPRESS is an essential component for nitrous oxide system installations and upgrades on high-performance vehicles. This precision-engineered fitting serves as the critical connection point between your nitrous bottle and the fuel or nitrous distribution lines in your engine bay. Whether you're building a street-legal boosted setup or fine-tuning an existing nitrous system, this nipple fitting ensures reliable flow control and leak-free operation under pressure.

Manufactured to NITROUS EXPRESS's exacting standards, the 6AN ORB fitting features a true ORB (O-Ring Boss) design that creates a positive, vibration-resistant seal without relying on thread tape or sealant compounds. The 6AN sizing indicates a -6 AN hose adapter specification, making it compatible with standard braided stainless steel nitrous and fuel lines commonly used in performance applications. The compact form factor—weighing just 0.06 lbs and measuring 1.9 x 1.55 x 4.9 inches—allows for flexible routing and installation in tight engine compartments while maintaining structural integrity under the high pressures typical of pressurized nitrous bottle systems.

This nipple fitting is ideal for enthusiasts upgrading existing nitrous kits, replacing worn or damaged fittings, or assembling complete custom systems tailored to specific fuel or nitrous delivery requirements. Proper installation requires hand-tightening the ORB connection until the O-ring compresses firmly—over-torquing can damage the seal. Compatible with all standard -6 AN braided hose lines and nitrous bottle assemblies, this NITROUS EXPRESS fitting delivers the durability and reliability demanded by serious performance builders and tuners.
