How to find the right Automotive Performance Nitrous Oxide Braided Hoses AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Automotive Performance Nitrous Oxide Braided Hoses

Liner material
Use PTFE (Teflon)-lined stainless braided hose rated for nitrous pressure. Rubber-lined hose is not suited to sustained nitrous pressure.
AN size
Size the feed line to the system's horsepower and length, typically -4 for moderate systems and larger AN for big or direct-port systems. An undersized line causes pressure drop and inconsistent flow.
Length and routing
Route away from exhaust, sharp edges and suspension travel, with the fewest possible fittings. Heat raises line pressure and abrasion leads to failure.
Fittings
Use AN fittings rated for PTFE hose. These differ from fittings for rubber hose. Fittings meant for rubber hose won't seal properly on PTFE.

Brands that matter

  • Nitrous Express: Pre-made nitrous feed lines in common lengths.
  • NOS: Feed lines for its kits.
  • Earl's: PTFE hose and matching fittings.
  • Russell: PTFE braided hose and fittings.

What to avoid

  • Rubber-lined braided fuel hose used as a nitrous feed
  • Mixing PTFE hose with rubber-hose fittings
