Series EWC439
Custom Made Hose

Series EWC439 is a heavy duty oil suction and discharge (OS&D)/dock hose for transferring
oil between tankers, barges, and storage tanks. The hose construction incorporates a
specially formulated tube that resists media to 50% aromatic content. The wire helix
provides full suction capability, kink resistance and a path to conduct a static electrical
charge to ground. The rugged corrugated cover provides additional flexibility and is
resistant to abrasion, mild chemicals, oil and weathering. Series EWC439 meets all United
States Coast Guard (USCG) requirements for dock/OS&D hose.
NOTE: For 300 psi hose, refer to Series EWC356. Other customized versions of this product
are available. Contact Parker.
