Looking to assemble pushlock hose fittings like a pro? Follow these easy step-by-step instructions to install Speedflow 400 Series pushlock hoses with precision. This guide is ideal for motorsport, performance, or automotive enthusiasts in New Zealand using AN fittings.
🔧 Tools You'll Need:
-
Vice
-
Vice Jaws (preferably soft jaws to avoid damage)
-
Hose Cutters
-
Liquid Soap (used as a lubricant)
✅ Tip: For best results, use Speedflow’s 400 Series Hose Cutters (Part #433-12) — available at anfittings.co.nz
Step 1: Cut and Prepare the Hose
-
Choose the correct size hose for your AN fittings.
-
Measure and cut the hose to your desired length using a sharp hose cutter or blade.
-
Ensure the cut is clean, square, and free of any residue or frayed material.
🚫 Avoid crushing the hose during cutting – clean edges ensure a secure seal.
Step 2: Secure the Hose End
-
Firmly place the hose in a vice using vice jaws.
-
For angled pushlock fittings, use the correct adapter in the vice and screw the angled fitting into position.
-
Ensure the fitting is tight in the vice to prevent movement.
Lubricate the barbed end of the fitting using liquid soap — avoid oils or grease as they can interfere with hose performance.
💡 Pro Tip: Liquid soap dries, preventing slippage over time, unlike oil-based lubricants.
Step 3: Attach the Hose
-
Align the hose with the barbed tail of the fitting.
-
Push the hose onto the fitting in one continuous motion until it seats firmly under the collar.
Some resistance is normal as the hose moves over the barbs.
♨️ Hot Tip: Warm the hose in hot water for 30 seconds to soften it — this makes pushing it on much easier.
-
Remove from the vice and repeat for the opposite end.
Step 4: Final Inspection & Pressure Test
Before installing your assembled hose on your vehicle:
-
Clean and visually inspect the hose and fitting.
-
Pressure test the assembly to the required pressure for your application.
-
Verify there are no leaks and the connection is tight and secure.
Once verified, your pushlock hose assembly is ready for performance use!
