Obsolete: Large Diameter Custom Made Heavy-Duty Dredge/Sand Suction Hose, Series EW708

Brand: Parker Hannifin

Parker's Series EW708 Large Diameter Custom Made Heavy Duty Dredge/Sand Suction Hose provides excellent heavy duty service as a flexible connection across multiple high pressure dredging and bulk transfer and applications. 

The thick rubber tube provides additional resistance to abrasive materials going through the hose and the cover provides resistance to abrasion and weathering for maximum performance. 

The basic hose construction may be modified to customer-specified requirements, including brand, length pattern and built-in coupling configurations. 

Parker will quickly design and build a custom made product to satisfy specific application requirements and will drop-ship in protective packaging, eliminating the cost of additional handling and the need to compromise on hose performance.
