1/8in. Cone Ferules-8pk.

The 1/8in. Cone Ferules-8pk. from Nitrous Oxide Systems is a precision brass compression fitting component essential for high-performance nitrous oxide system installations. These cone ferules are designed for mechanics and performance enthusiasts building or maintaining NOS systems, where reliable connections prevent dangerous leaks and ensure consistent boost delivery. Each pack contains eight individual ferules, offering enough stock for multiple system builds or replacements across your shop.

Constructed from brass, these 1/8-inch cone ferules function as compression seals within NOS distribution tubing and manifold connections. The cone geometry creates a tight, wedge-style seal when properly tightened onto matching fittings, preventing oxidizer escape at critical pressure points. Brass material resists corrosion from nitrous oxide exposure and maintains its dimensional integrity across repeated thermal cycles, ensuring longevity in both street and drag racing applications. The ferule design requires no additional sealant tape or compound when installed correctly, simplifying assembly and reducing contamination risk.

Professional technicians and experienced home builders benefit most from stocking these ferules when assembling complete nitrous systems or servicing existing installations. Compatibility depends on matching your system's tubing outer diameter and fitting port specifications to the 1/8-inch specification. Proper installation requires hand-tightening the ferule onto tubing, inserting into the port, then wrench-tightening the compression nut to seat the cone—over-torquing will damage the brass and create leaks. These ferules are standard across most Nitrous Oxide Systems products and industry-compatible platforms using compression-style connections.
