• For Use With #660 Style Bottle Valves
• CNC Machined Aluminum
• Includes Gasket
• For Use With 6AN Main Feed Line

One Piece Design:
Instead of using a 2 piece design like the #326 bottle valves, #660 valves use a 1 piece bottle nut and nipple that is sealed with the supplied Teflon gasket.

Ê

Application:
#660 style bottle nuts are used by some nitrous companies such as NOS, and on some mother bottles. Nitrous Outlet, Nitrous Express, Zex and many other nitrous companies have switched to using the two piece #326 design.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
