12 in Hose Extension

The Westward 4BY84 is a 12 inch polyurethane hose extension with 1/8 MNPT male connections on both ends. It is rated for a maximum pressure of 3,500 psi and features plated steel ends secured by hydraulic crimping. A coupler is included with the hose. This product is intended for users who need a short, high-pressure hydraulic line extension.

Replaces worn hydraulic lines

This extension replaces a damaged or leaking hose segment in a hydraulic circuit where 1/8 MNPT threads are used. The jump is worth it when the existing hose has cracked, the fittings have corroded, or the assembly length must be increased by 12 inches. The 3,500 psi rating must match or exceed the system operating pressure for safe operation.

Check thread size and chemical warning

Verify that both connection ports on your equipment use 1/8 MNPT threads before ordering. Confirm the system pressure does not exceed 3,500 psi. Be aware this product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

What thread size does the 12 in extension use to connect?

The hose extension has 1/8 MNPT male threads on both ends for direct connection to compatible fittings.

How do I install the extension without damaging the crimped ends?

Thread each 1/8 MNPT end by hand until snug, then tighten gently with a wrench on the plated steel hex flats — do not clamp the rubber hose body.

When should I replace the 12 in polyurethane hose extension?

Replace it if the transparent hose shows cracks, bulges, abrasion, or if the plated steel ends leak or corrode under 3,500 psi service.
