Not every request starts with a part number. You may have a photo of an unknown coupler, a machine that is difficult to connect under pressure, a high-flow circuit creating heat, a recurring leak, or a new OEM layout that needs dimensional review.
Send us what you have, including photos, drawings, CAD files, measurements, or system requirements, and Stucchi will help evaluate the next step.
What Hydraulic Challenge are You Trying to Solve?
Hydraulic connection problems are not always solved by matching a part number. Coupler size, thread type, pressure rating, flow requirement, fluid compatibility, available space, machine layout, and operating environment all affect the correct recommendation.
Use the Technical Help Desk when you need help with one of these common situations:
Identify or replace a component – Upload a photo, measurement, or part number so Stucchi can help identify a coupler, fitting, thread type, or replacement option.
Size or select a hydraulic coupling – Share flow rate, pressure, temperature, fluid type, duty cycle, or application details for support with coupling selection.
Troubleshoot a field issue – Get help with leaks, seal wear, contamination, brinelling, pressure lock, connection difficulty, pressure drop, overheating, or residual pressure.
Review an OEM or custom application – Submit CAD files, drawings, diagrams, or machine requirements for support with multi-coupling plates, custom solutions, prototypes, retrofits, or hydraulic interface design.
Need help with something else? Our hydraulic engineers are up for the challenge. Reach out via phone, chat, form, or email, and let us know how we can help.
Upload a Photo, and We Can Help Identify It
Not sure what coupling you have? Upload a clear photo of the coupler, hose assembly, thread connection, or machine interface, and Stucchi can help identify the component visually. This supports operators, maintenance teams, distributors, and engineers who may not have a part number, product series, or drawing available.
Helpful uploads include:
- Coupler face or side profile
- Thread or port connection
- Full hose assembly
- Machine or attachment connection point
- Damaged, leaking, or failed component
- CAD files, drawings, diagrams, or application photos
For OEM and engineering requests, uploaded files help Stucchi evaluate fit, function, sizing, and system requirements before recommending the next step.
What to Include with Your Request
Share as much information as you have. You do not need every detail to submit a request, but photos, drawings, measurements, and basic application data help Stucchi review your challenge faster.
| Helpful Detail | Why It Matters |
|---|---|
| Equipment type, brand, and model | Identifies the machine platform and likely hydraulic setup |
| Attachment or tool | Helps evaluate flow, pressure, duty cycle, and connection frequency |
| Current coupler, part number, or body size | Supports identification, replacement, or interchange review |
| Thread type or port connection | Helps confirm fit and compatibility |
| Flow rate and pressure | Supports sizing, pressure drop, and rating review |
| Fluid type or media | Helps evaluate material and seal compatibility |
| Operating environment | Accounts for dirt, mud, washdown, salt, cold, heat, or corrosive exposure |
| Connection issue or desired outcome | Clarifies whether you need identification, troubleshooting, replacement, retrofit, or custom design |

Frequently Asked Questions
Can Stucchi help me identify an unknown hydraulic coupler from a photo?
Yes. If you do not know the part number, product series, thread type, or body size, upload a clear photo through the Technical Help Desk form. Helpful photos include the coupler face, side profile, thread or port connection, hose assembly, and machine or attachment connection point. Stucchi can use those details to help identify the component and determine what information is needed next.
What information should I provide to size or select a hydraulic quick coupling?
The most helpful details include equipment type, attachment or tool, flow rate, working pressure, peak or residual pressure, fluid type, operating environment, thread or port connection, and desired outcome. If you do not have every detail, submit what you know and include photos, drawings, or measurements. Stucchi can use that information to help evaluate coupler sizing, pressure drop, compatibility, and application requirements.
Can Stucchi help troubleshoot pressure drop, overheating, or high-flow hydraulic performance issues?
Yes. Stucchi hydraulic specialists can review high-flow hydraulic applications where pressure drop, overheating, restricted flow, or coupler failure may be affecting performance. In many cases, these issues involve more than the coupler alone. Flow rate, hose size, adapters, fittings, circuit layout, duty cycle, and quick-disconnect selection can all affect heat generation and hydraulic efficiency.
When submitting a request, include your flow rate, working pressure, attachment type, equipment model, current coupler size, and any symptoms you are seeing. Stucchi’s hydraulic pressure drop resources explain how flow restriction, pressure loss, and coupler sizing affect system performance in high-flow applications.
Can Stucchi hydraulic engineers review CAD files, drawings, or OEM application details?
Yes. OEMs, engineers, distributors, and equipment manufacturers can submit CAD files, drawings, diagrams, photos, and application details through the Technical Help Desk. Stucchi can help review dimensional requirements, mounting constraints, connection interfaces, multi-coupling layouts, prototype needs, custom solutions, or design-in questions.
