Is the Metric ISO 12151-2 24° Cone O-Ring Straight Hose Coupling compatible with DN2 and DN4 measuring hoses and supplied with a clamping sleeve?

Yes. The Metric ISO 12151-2 24° Cone O-Ring Straight Hose Coupling is compatible with DN2 and DN4 measuring hoses and is supplied complete with a clamping sleeve. The straight measuring-hose version fits DN2 or DN4, includes the clamping sleeve for quick, secure installation, and features a 24° cone with NBR O-ring, high-quality steel construction with zinc‑nickel coating, and working pressures from 250 to 630 bar (size-dependent). Temperature range: -30°C to +120°C.

Can the Metric ISO 12151-2 24° Cone O-Ring Straight Hose Coupling withstand continuous operation at its maximum rated pressures (250–630 bar) without reducing service life?

Metric ISO 12151-2 24° Cone O-Ring Straight Hose Coupling: Yes — with qualifications. The coupling is rated for working pressures of 250–630 bar depending on size and is manufactured from high-quality steel with a corrosion‑resistant zinc‑nickel coating and an NBR O‑ring seal. These features, plus availability in lighter (L) and heavier (S) series, make it suitable for continuous high‑pressure use in demanding hydraulic systems. However, continuous operation at the maximum rated pressure will affect service life compared with operation at lower pressures. Factors that influence longevity include: - actual system pressure vs. rated pressure (peak fluctuations and spikes), - duty cycle (continuous vs. intermittent), - temperature (−30°C to +120°C rating; higher sustained temperatures accelerate wear of NBR), - fluid type and contamination, - dynamic stresses (vibration, bending, impulse loads), - correct assembly and use of the provided clamping sleeve, - maintenance practices. If your application subjects the coupling to sustained maximum pressure, repeated pressure spikes, elevated temperatures near the upper limit, or harsh contaminants, consider selecting the S (heavy) series, sizing conservatively, implementing pressure surge protection, and establishing regular inspection and maintenance to preserve service life.
