The ZEX NS6687 is a 1/8" NPT bulkhead fitting with backing nut, designed for use in nitrous oxide and fuel line installations where a secure, leak-free panel or firewall pass-through is required.

Key Features:

  • Thread Size: 1/8" NPT (National Pipe Thread)
  • Includes backing nut for secure bulkhead panel mounting
  • Universal fitment — compatible with nitrous oxide and fuel line applications
  • Precision-machined construction for reliable, leak-free performance
  • Part of the ZEX nitrous accessories and fittings product line
