Car Fuel Line Quick Release Nylon Connector 7.89mm ID

The NIGHTKIST Car Fuel Line Quick Release Nylon Connector is a reliable, tool-free solution for fast and secure fuel line connections. Designed for 6 mm inner diameter nylon hoses and 8 mm inner diameter rubber hoses, this connector lets you push in to connect and pull out while pressing the locking buttons to disconnect. Built from durable nylon, it withstands common automotive fuels and harsh temperatures, making it ideal for maintenance, testing, and quick-rerouting tasks without the need for tools.

With a compact 7.89-ID6 interface on both ends, the system supports line-to-line and line-to-equipment connections. The integrated seal provides tightness for fuel types including petrol and diesel, while the not-auto-sealing design ensures you actively monitor sealing integrity in your setup. The connector is rated for a maximum back pressure of 500 kPa (5 bar) and operates across a wide temperature range from -40°C to 115°C (-40°F to 239°F), making it suitable for a variety of climates and vehicle applications.

Benefits & Tips

• Fast, tool-free assembly: save time on installations, testing, or temporary setups by simply pushing the hose onto the connector and locking it in place.
• Versatile configuration: use for line-to-line or line-to-equipment connections, enabling quick hose swaps and routing changes without disassembling other components.
• Practical maintenance advice: always verify hose ID compatibility (6 mm nylon or 8 mm rubber), ensure the seal is intact, and confirm the connection remains within the 5 bar maximum pressure during use.
