Hydraulic Hose Coupler Repair

If you need an easy and permanent fix for a broken hydraulic hose on your convertible top, Custom Hose Tech may be the solution. Our couplers are explicitly designed to repair or reconnect standard hydraulic hoses in modern convertible top hydraulic systems. They can often be done on the car with essential hand tools. So if you’re sick of constantly replacing your leaking hoses, give our couplers a try today.

Hoses are crimped the same on both their interior and exterior as factory connectors. Most hydraulic systems that use these lines with a small bore (internal) diameter operate at a peak pressure no higher than 200 bar or 2900 psi. Custom Hose Tech have been tested to see if they can handle 10,000 pounds per square inch without breaking– which they passed successfully. Convertible hydraulic hoses in various-roofs and retractable hardtops made by:

We have a comprehensive list of makes and models that our repair coupler will fit, including but not limited to Audi, Bentley, BMW, etc. Please see the Hose Coupling Installation Requirements section below to determine if our product is right for you.

Coupler Installation Requirements

  1. Couplers fit only factory-installed hoses with an internal (bore) diameter of 1.8mm and 2.0mm and 4.5mm outer diameters. To identify your hose’s bore diameter, check the printing on your damaged OEM hose. Hose Couplers will then fit hoses designated as AF1.8 or DN1.8 for a 1,8m Bore, while those measuring 2 mm would be AF2. or DN2. The hoses’ outer diameters must be 4.5mm. Still, they can vary between 4.45mm and 4.55mm​ You can measure the outer hose diameter with a precision vernier caliper for more accurate results.
  2. The Hose Coupler is a device that can be used to reattach hoses together as long as the minimum length from the metal connector is .750″ (19mm). If unnecessary, don’t cut the hose too close to where it meets the fitting.
  3. The hose coupling can’t obstruct the top mechanism, and the fixed hose needs a big enough bend radius not to fold or collapse.
  4. Installers need enough space to maneuver their tools.
  5. The Hose Coupler is a single-use product; it cannot be reused after being crimped.

Hose Coupler Installation Instructions

Step 1: Before beginning any repairs, ensure that the ignition is switched OFF and the hydraulic system is no longer pressurized.

Step 2: Make cuts perpendicular to the hose with a utility knife to remove the damaged section. This will ensure square, clean-cut hose ends. Use a wood block to support the hose beneath it so the blade moves quickly through without resistance. Do not use wire/diagonal/side cutters, saws, or cut-off wheels, as these tools distort the original shape of the housing and cause particles to loosen and enter into the hydraulic system, which will then fail.

Step 3: Hand-tighten both locking nuts on the coupler. With one hand, twist and insert the hose strongly into the repeater until it feels snug.

Step 4: To uncouple the hose, unscrew the crimping nut and slide it away from the Hose Coupler.

Step 5: To secure the Hose Coupler, grip it firmly in your hand or use locking pliers around the central hexagon of the body.

Step 6: With the abrasive side of the sandpaper facing out, fold it over the hose and clamp it down with narrow nose pliers. This will give you a good grip while protecting your hose from being damaged by the pliers. Take your time pushing and twisting the hose into position in the Hose Coupler—you want as little gap as possible between them. If you need to, use a flashlight and magnifier to check that everything is lined up correctly before moving on.
