DIN 3016 is the specific section of the German industrial standard that defines the requirements for light-duty constant tension (spring) hose clamps. This standard establishes the precise dimensions, material specifications, performance criteria, and testing methods for these clamps, ensuring they provide reliable, maintenance-free sealing in applications with frequent thermal cycling, particularly where space and weight are considerations.
Rubber lined P clamp is one type of DIN 3016 clamps. They are featured a zinc-plated mild steel band with an inner EPDM rubber lining, providing both robust metal support and vibration-dampening protection.
Key Features of DIN 3016 clamps
Spring Steel Construction:
The clamp is manufactured as a single piece from high-carbon spring steel.
Surface Finish: To provide corrosion resistance, these light-duty clamps are typically electro-galvanized (zinc-plated), though stainless steel versions are also available for harsher environments.
Constant Tension Principle:
The core function is to automatically maintain a consistent clamping force on a hose connection.
As the hose and fitting expand and contract with temperature changes, the spring steel clamp compensates, ensuring a leak-free seal whether the system is hot or cold. This prevents leaks from contraction and damage from over-compression during expansion.
Common Applications
DIN 3016 clamps are designed for specific, light-duty OEM applications:
Automotive Industry: Frequently used on smaller coolant hoses (e.g., heater cores), vacuum lines, and other secondary fluid connections within the engine bay where large thermal cycles occur.
Appliances: Connections in washing machines, dishwashers, and other household appliances involving water lines.
General Light Industrial Equipment: Low-pressure fluid and air connections on machinery.
DIN 3016 specifies a light-duty, constant tension hose clamp engineered for applications with thermal cycling where lower clamping force is required. Its electro-galvanized spring steel construction and narrow design make it a cost-effective and reliable solution for OEMs in the automotive and appliance industries.
