Is the Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7 compatible with hoses of differing outer diameters within specified D1 tolerances?

Yes. The Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7 is compatible with hoses whose outer diameters fall within the specified D1 tolerances. The clamping sleeve is designed to engage the hose within the stated D1 (outer diameter) range; as long as the hose OD lies inside those nominal tolerances, D2 (inner diameter) and D3 (lock diameter) dimensions and the sleeve geometry will provide correct seating and mechanical lock without additional machining. Using a hose outside the specified D1 tolerance can lead to improper clamping, leakage or sleeve failure, so verify the hose OD matches the MC-BP7 D1 specification before installation.

Can the Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7 be reused after removal without machining?

Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7: No. The MC-BP7 clamping sleeve is specified for installation with no machining, but once removed it cannot reliably be reused because its lock diameter (D3) and clamping geometry are permanently deformed during initial crimping. Reuse risks poor sealing and mechanical failure. Replace the collet with a new MC-BP7 to ensure proper fit and safety.

Does the Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7 require lubrication before installation?

Collet for R7 thermoplastic hoses, 1SC, carbon steel, type MC-BP7 does not require lubrication before installation. The provided description for the MC-BP7 clamping sleeve indicates "Installation - no machining" and specifies dimensions (D1 outer diameter, D2 inner diameter, D3 lock diameter) and material (carbon steel, galvanized). These details imply the part is designed for straightforward assembly onto the hose without additional surface preparation such as lubrication. Using lubricant could interfere with the clamping action or the galvanised finish. Follow the manufacturerâs specific assembly instructions if available; otherwise install dry, ensuring correct alignment of diameters and secure locking per standard practice.
