Anesthesia & Breathing Circuit Fittings
Custom plastic connectors and fittings for anesthesia delivery systems and respiratory circuits. 22mm standard and custom sizes. OEM/ODM with NDA from Guangdong, China.
About Anesthesia Circuit Components
Anesthesia breathing circuits and ventilator circuits rely on a range of plastic connectors and fittings to deliver anesthetic gases and oxygen to patients. These components must meet strict dimensional standards (ISO 5356 for 22mm and 15mm connectors), be chemically compatible with anesthetic agents, and maintain secure connections under respiratory pressures.
EKINSUN manufactures custom anesthesia circuit components from medical-grade plastics. We work from engineering drawings, existing samples, or hand-sketched designs to produce the exact fitting you need — including configurations not available from standard catalog suppliers.
Components We Manufacture
- 22mm and 15mm connectors — ISO 5356 compliant push-fit connectors for breathing circuit assembly
- Elbow connectors — 22mm elbows in various angles for patient interface connections
- T-pieces and Y-pieces — for circuit branching and sampling port addition
- Swivel connectors — rotating joints to prevent circuit torsion at patient interface
- Reservoir bag mounts — connectors for breathing bag attachment
- CO₂ sampling ports — integrated or add-on sampling luer ports
- Custom fittings — non-standard sizes and configurations from your drawing
Ordering from a Hand Drawing or Sample
If you need a fitting that is discontinued, unavailable from standard suppliers, or specific to your equipment, we can manufacture it. Send us a hand sketch with dimensions, a sample part, or an engineering drawing — we will produce a CAD model for your approval and then manufacture the parts.
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. This is one of our most common requests. Send us a sample of the fitting you need, a hand sketch, or dimensions — we reverse-engineer and produce replacement parts. This is particularly valuable for older anesthesia machines or equipment where OEM parts are no longer available.
Medical-grade polycarbonate (PC) and ABS are broadly compatible with common volatile anesthetic agents including sevoflurane, desflurane, and isoflurane. For specific chemical compatibility requirements, we advise on material selection based on your application.
