    ### Marineflex Hose 38mm x 20m Roll

Choose this 38mm hose for bilge pumping or caravan and RV waste drainage. Product 386704 is supplied as 20 m roll, so match both the connection size and the supplied quantity to the planned run.

The smooth-bore hose is lightweight and flexible, with UV stability for the stated applications. It operates from -5°C to 60°C and conforms to AS 2070 for plastics in food contact.

This hose is not suitable for pressure applications. Choose it for the listed bilge or waste duty and check the required diameter before planning the roll quantity.

Measure the required route before choosing the quantity, allowing for the connections at each end. Use the hose’s stated application and limits as well as its diameter when matching it to the system.

### Choosing and using this product

For this version, size: 38mm. Use that specific detail when comparing the item with your existing equipment or planned installation. Other sizes and configurations in the range should be checked separately rather than treated as equivalent.

Keep service points accessible and follow the relevant system instructions for fastening, sealing and hose support. Avoid forcing a hose or thread to compensate for an unsuitable fitting. Confirm the finished connection and normal system operation before putting the installation back into use.

When comparing alternatives, use the specified material and intended application rather than assuming every marine fitting is suitable for every liquid. Keep the part reference with the plumbing records so future spares can be matched to the connection actually installed.

For a replacement, inspect the existing fitting and adjoining hose before ordering. Consider the direction of the connection as well as its size. An elbow, straight fitting or barbed tail changes the route and clearance needed even when the nominal connection size is similar.
