I need a cylindrical tube made of high-durometer silicone with the following specifications: - Inner diameter: 2.25 inches - Outer diameter: 2.5 inches - Length: 5 inches - Color: Black - One end capped with rubber cap featuring a 1-inch diameter hole (see pic, which is of a detachable sleeve, black with hole in center. I'd like this to be part of the tube/cylinder, and not detachable or separate) - Other end to have a beveled notch about 1/8in from the top to hold the plastic rounded piece that will snap into place and be air tight.. You see in the pic of the clear rounded top. It has a lip on the end. I'd like the silicone cylinder to have a way of fitting that lip into the top. Ideal the silicone is firm enough to withstand 4lbs of pressure, but flexible enough to stretch so the top part can fit into a beveled slot about 1/8 inch from the top of the cylinder. Ideal skills and experience: - Expertise in silicone fabrication - Precision in achieving specified dimensions - Ability to work with high-durometer silicone - Experience in producing rubber-capped components Please provide samples of similar work and estimated delivery time.

As a licensed structural engineer with extensive experience in mechanical engineering and design, I am proficient in working with different materials including the high-durometer silicone you require for this project. Over the course of my 12-year career, I have led numerous projects that demanded precision and attention to detail, which aligns incredibly well with your need for specific measurements on this silicone tube fabrication. Moreover, I understand the importance of not just meeting but exceeding client expectations. My team's work is always precise, in accordance with required codes and standards, and designed to deliver optimal performance. I have also familiarized myself with the kind of crossover connections your project necessitates after studying the images you've provided. Hence, constructing a secure beveled top to tuck in that plastic piece would not be an issue for us; and we will ensure it is airtight as required. Lastly, one of my greatest strengths lies in my ability to effectively communicate and collaborate with clients throughout the scope of a project. Over time, this has translated into successful problem-solving skills and high levels of adaptability - both paramount traits given the complexity detailed in your description. Considering your timeline constraints on this silicone tube fabrication project, my swift turnaround time ensures your needs will be met without compromising quality or precision. Looking forward to accomplishing this task together!
