750 x Carmo 03‑601 HF/Ultrasonic Weldable Threaded Flange – G 3/4" PVC & PVC/PUR

As the UK distributor for Carmo, we supply the original 03‑601 HF/ultrasonic weldable threaded flange, manufactured in Denmark to Carmo’s renowned quality standards. This durable, high‑performance flange features an internal G 3/4" female thread and forms the core of Carmo’s modular valve system, making it an essential component for a wide range of inflatable, marine and industrial applications.

Engineered for High‑Frequency (HF) and ultrasonic welding, the 03‑601 flange bonds securely to PVC and PUR‑based materials, ensuring strong, reliable welds even in demanding environments. Its thoughtful design incorporates small protrusions on the underside, preventing unwanted sealing against the material during vacuum applications and maintaining consistent airflow, stability and reliable functionality.

This threaded flange is widely used across marine, industrial and technical textile sectors, including:

• Inflatable boats and rafts
• Buoys, booms and maritime structures
• Water tanks and ballast bags
• Water bags and flexible reservoirs

As part of Carmo’s wider modular valve system, the flange is compatible with Carmo’s full range of valves, including inflation, vacuum, pressure and over‑pressure relief options—allowing manufacturers to build versatile, multi‑functional assemblies from a single, standardised interface.

Manufactured in Denmark using high‑precision injection moulding, the 03‑601 offers excellent dimensional accuracy, long‑term durability and dependable performance. Carmo’s production approach also prioritises sustainability, with careful attention to material selection and environmental impact throughout the manufacturing process.
