Submit your application details and FasTest engineers will evaluate your requirements and recommend the best sealing connection solution—whether that’s a standard product, a modified connector, or a fully custom design.
Not sure which FasTest connector is right for your port, pressure, or media? That’s exactly what the Application Evaluation is for. Our product and custom engineers review thousands of applications every year across automotive, aerospace, HVAC-R, compressed gas, medical, fluid power, and appliance industries. Send us your application details and we’ll do the engineering work to identify the right solution.
There’s no cost and no obligation. Whether you have a straightforward threaded port that needs a standard connector or a complex sealing challenge that requires custom engineering, the Application Evaluation is the fastest way to get a recommendation from someone who has solved problems like yours.
The Application Evaluation process is designed to be fast and thorough:
The entire process starts with the form below. The more complete your submission, the faster and more accurate the recommendation.
The Application Evaluation form asks for specific technical details so our engineers can make an accurate recommendation. Here’s what each key field is used for and how to prepare:
| Form Field | What to Provide & Why It Matters |
|---|---|
| Test Pressure | The pressure at which you need to test or seal. Include units (psi, bar, kPa). This determines connector pressure rating and seal material selection. |
| Test Temperature | The temperature of the media or environment during testing. Extreme temperatures affect seal material compatibility and connector performance. |
| Test Medium | The gas or fluid used in your test (air, nitrogen, helium, water, oil, refrigerant, etc.). Media compatibility drives seal material and connector body material selection. |
| Flow Required | If your application involves fluid transfer or requires a specific flow rate, include the value. This affects connector bore size and hose selection. |
| Acceptable Leak Rate | Your pass/fail threshold for the test. This helps our engineers select the right seal type and sealing method for your sensitivity requirements. |
| Type of Test | Bubble leak, pressure decay, proof test, tracer gas, helium mass spectrometer, etc. Different test types have different sealing requirements. |
| Type of Application | Manual or automated? Twist-to-seal or lever action? Pneumatically operated? This determines the actuation method and station integration approach. |
| Surface to be Sealed | Machined, cast, threaded, or other. Surface finish directly affects seal design—rough castings need different sealing approaches than precision-machined bores. |
| Diameter to Seal / Grip | The ID or OD of the port or tube you need to seal or grip. Precise dimensions ensure the right connector size and seal fit. |
| Drawings / CAD Models | Attach port drawings, CAD files, or dimensioned photos if available. Visual references dramatically speed up the evaluation and reduce back-and-forth. |
Don’t have all of this information? That’s okay. Fill in what you can and our engineers will follow up to gather any missing details. A partial submission is always better than no submission—it starts the conversation.
Many visitors assume the Application Evaluation is only for complex or custom sealing challenges. In reality, it’s the best starting point for any connector selection question:
FasTest offers the Application Evaluation at no charge because it’s the most efficient way for both sides to get to the right answer. Our engineers review your application, match it against our standard product library and custom capabilities, and provide a recommendation—all before any purchase commitment.
There’s no sales pressure, no mandatory follow-up calls, and no obligation to proceed. If a FasTest solution isn’t the right fit for your application, we’ll tell you. Our reputation is built on solving real problems, not on overselling connectors into applications where they don’t belong.
FasTest engineers evaluate thousands of applications every year for manufacturers across automotive, aerospace, HVAC-R, compressed gas, medical, fluid power, and appliance industries. Here’s what sets the evaluation apart:
Based on the information submitted, FasTest products engineers evaluate the application and select the most suitable connector for the application. For custom products, a formal quote is then created for that specific application. When the order is received, the custom products engineers design, develop and manufacture the connector in accordance to your specific requirements. Custom products connectors are non-returnable. Therefore, it is important to submit all the information requested clearly and accurately.
Please complete as many fields as possible.
An Application Evaluation is a free engineering review of your sealing connection requirements. You submit your application details—port geometry, pressure, media, and operating conditions—and a FasTest engineer recommends the right connector solution, whether that’s a standard product, a modification, or a custom design.
No. The Application Evaluation is completely free with no obligation. FasTest engineers review your application and provide a recommendation at no charge.
Most standard product evaluations are turned around the same business day. Custom applications typically receive an initial concept response within 1–2 business days. Complex projects that require detailed engineering analysis may take slightly longer, and your FasTest contact will communicate the timeline.
Submit what you have. Our engineers will follow up to gather any missing information. A partial submission is always better than no submission—it starts the conversation and ensures we can begin evaluating your application.
Yes. You can attach files to the form, email drawings directly to fastsales@fastestinc.com, or share them with your local FasTest distributor. Dimensioned port drawings, CAD models, and photos of the connection point dramatically speed up the evaluation process.
No. The Application Evaluation is for any connector selection question—standard products, modified standard products, and custom designs. If you’re not sure which FasTest connector fits your application, this is the best place to start.
FasTest serves automotive and EV manufacturing, aerospace, HVAC-R, compressed gas, medical and life science, fluid power, and appliance industries. Our engineers have experience across all of these sectors and can evaluate applications in any of them.
Yes. Distributors and sales engineers frequently submit Application Evaluations on behalf of end customers. Include the end-user’s application details and your contact information, and FasTest will work with you to deliver the recommendation.
We’ll tell you. If a standard, modified, or custom FasTest solution isn’t the right fit for your application, our engineers will explain why and, where possible, suggest alternative approaches. We’d rather give you an honest answer than sell a connector into an application where it won’t perform.
Absolutely. You can call FasTest at 800.444.2373, email fastsales@fastestinc.com with your application details and drawings, or download the PDF Application Evaluation form and submit it via email. The online form is the fastest route, but all channels reach our engineering team.
