HySecurity MX4029 is a fittings kit identified as a 1/2 inch hose with a 1/4 inch quick-disconnect fitting arrangement. In HySecurity service work, hose and quick-disconnect kits are used to replace damaged, leaking, or worn hydraulic/pressure-line connections while keeping the operator serviceable. This part should be treated as a specific HySecurity service kit, not a generic hydraulic hose assembly. A correct match depends on hose size, fitting type, quick-disconnect style, thread/seal type, pressure rating, hose length, and the way the line connects to the hydraulic panel or operator assembly. Similar-looking fittings can fail or leak if the sealing face, thread form, or quick-disconnect type does not match. Before ordering, verify the original parts list, inspect the existing fitting, and confirm whether the operator requires MX4029 or another hose/fitting kit.
This part is commonly associated with the following HySecurity applications when the installed equipment and parts diagram call for this exact part number:
| Manufacturer | HySecurity / Nice HySecurity |
| Product Type | Hose and fittings kit |
| Part Number | MX4029 |
| Application | Hydraulic or pressure-line service |
| Compatible Operator Type | Select HySecurity systems by parts diagram |
| Included Components | 1/2 inch hose and 1/4 inch quick disconnect reference |
HySecurity parts often vary by operator family, production date, voltage, hydraulic layout, arm length, handing, and installed accessory package. Match the original part number and use the operator parts diagram before treating any related number as a direct replacement.
Gate and barrier operator service can involve stored mechanical force, moving arms, hydraulic pressure, and high-voltage circuits. Do not bypass safety devices or force the operator to run with missing protection. Electrical, hydraulic, or unsafe movement problems should be handled by a qualified gate technician.
Public references describe MX4029 as a fittings kit with 1/2 inch hose and a 1/4 inch quick-disconnect connection.
No. MX4029 should be ordered only when the HySecurity parts diagram calls for this kit and the hose/fitting layout matches.
Quick-disconnects and hose fittings can share similar sizes but use different thread, seat, seal, or pressure designs. A mismatch can leak or fail.
Verify the operator model, parts diagram, hose length, fitting size, quick-disconnect style, and any pressure-rating requirements.
Yes. The operator should be secured, locked out, and safely depressurized before hydraulic hose or fitting work is performed.
