102x128 concrete pump hose 740AA with two VICTAULIC couplings, P 85 bar., L 5 m

102x128 pressure hose 740AA is used in concrete pumps for transporting concrete and liquid cement under intensive construction conditions. The larger inner diameter enables efficient transfer of higher material volumes, making the hose suitable for professional concreting systems.

The inner layer is made of smooth black NR rubber resistant to abrasive materials. The outer NR/SBR rubber cover provides resistance to weather conditions, deformation and mechanical wear. Four-layer steel wire reinforcement gives the hose high strength and allows it to withstand high working pressure.

The hose is resistant to low temperatures and abrasive materials. Supplied with crimped Victaulic type couplings and available in custom lengths.
