Custom Anesthesia & Breathing Circuit Fittings
Anesthesia and breathing-circuit fittings are the plastic connectors that join the components of an anesthesia or ventilator breathing system — masks, filters, catheter mounts, elbows, T-pieces, and corrugated tubing. Most use the 22mm and 15mm conical connections defined by ISO 5356, which is what allows components from different manufacturers to push-fit together securely.
EKINSUN injection-molds these fittings to ISO 5356 dimensions for OEM breathing-circuit assemblies, and also reverse-engineers replacement parts for equipment where the original components are no longer available.
Components We Manufacture

Materials & Compliance
Molded in medical-grade polycarbonate and ABS that are broadly compatible with volatile anesthetic agents such as sevoflurane, desflurane, and isoflurane. Custom sizes outside the ISO range are available on request, with USP Class VI / ISO 10993 material options, EO compatibility, and an NDA before reviewing proprietary designs.
Frequently Asked Questions
Yes. We manufacture 22mm and 15mm push-fit connectors to ISO 5356 dimensional standards, ensuring compatibility with standard anesthesia and ventilator breathing circuit components.
Yes. Send us a sample fitting or detailed measurements and we reverse-engineer and produce replacement parts. This is frequently requested for older anesthesia machines where OEM parts are no longer available.
Medical-grade polycarbonate and ABS are broadly compatible with volatile anesthetic agents including sevoflurane, desflurane, and isoflurane. For specific compatibility requirements, we advise on material selection based on your application.
Yes. We manufacture custom-sized connectors and fittings outside the ISO standard sizes. Send us your dimensional requirements or a sample of what you need to fit, and we produce a custom part.
