PRODUCT DESCRIPTION
Tecofi DI7140A Flexible Rubber Connector
DI7140A is a Tecofi (France) female-threaded rubber expansion joint: ACS EPDM bellows, epoxy-coated malleable cast iron BSP female ends, DN15 to DN50, for drinking water. This page covers DI7140A only; DI7140N has the same size range and length but uses EPDM, is for hot and cold water, and absorbs a smaller angular movement.

- Bellows (tube and surface): ACS EPDM rubber
- Reinforcement: Nylon fabric
- Ends: Malleable cast iron, BSP female thread to ISO 228-1; threaded ends epoxy coated, 50 µm
- Fluids: Drinking water
- Length L: 200 mm
- Movements: Lc 22 mm, Le 6 mm, Li 22 mm, angle 40°
- Max. working pressure: 16 bar
- Working temperature: -40°C / +120°C
- Pressure test: To EN 12266-1, DIN 3230 and ISO 5208

Lc: axial compression; Le: axial elongation; Li: lateral movement; A: angular movement (per the datasheet).
Difference from DI7140N
- Materials: DI7140A has ACS EPDM bellows and malleable cast iron ends with a 50 µm epoxy coating; DI7140N has EPDM bellows and malleable cast iron ends.
- Fluids: DI7140A states drinking water; DI7140N states hot and cold water.
- Angular movement: DI7140A absorbs 40°; DI7140N absorbs 20° (Lc, Le, Li are the same).
- Working conditions: the DI7140A datasheet states a maximum pressure of 16 bar and a temperature of -40°C / +120°C; the DI7140N datasheet states neither.
- Weights differ (for example DN15: 0.45 kg vs 0.70 kg; DN50: 2.54 kg vs 2.62 kg).
Applications
Reduces mechanical and thermal stress on pipes and related equipment (pumps, compressors, motors); absorbs vibration and noise; compensates axial, lateral and angular movement; corrects piping misalignment. Fluids: drinking water (per the datasheet).
Standards / Certifications
BSP female threaded ends to ISO 228-1; pressure tests to EN 12266-1, DIN 3230 and ISO 5208. The datasheet states the material “ACS EPDM” but does not explain the ACS marking and lists no specific approval (the “Product approvals” heading is empty).
