- 11,600 psi burst rating adds safety margin
Westward 4BY77 Hose Extension
The Westward 4BY77 is a 12-inch hose extension designed for fluid-transfer applications. It features 1/8 MNPT male connections on both ends for straightforward installation. The construction uses a nylon braid over rubber for durability. This fitting suits maintenance technicians and industrial operators needing a short, high-pressure link.
Sustained pressure performance
The hose handles a working pressure of 3,500 psi during continuous operation. Its minimum burst pressure is rated at 11,600 psi, providing a substantial safety margin. The nylon braid reinforcement resists expansion under prolonged load. The rubber core maintains flexibility without softening at the rated pressure.
Replaces worn short couplings
This extension replaces damaged or aged 12-inch hoses with 1/8 MNPT ends. The upgrade is worth it when the existing assembly shows cover wear, leakage at the crimp, or pressure loss. It restores full flow capacity in hydraulic or pneumatic circuits. Buyers needing longer reach or different thread sizes should look elsewhere.

Questions about this item
How much heat does the 12-inch nylon-braid hose generate when pressurised to 3,500 psi all day?
The hose is a passive rubber-and-nylon conduit; it produces no measurable heat itself, though the fluid inside may warm under sustained 3,500 psi working pressure.
What thread fittings must I already have to connect this 1/8 MNPT × 1/8 MNPT extension?
You need two female 1/8 NPT ports — one on the supply side and one on the tool side — to screw the male ends directly in.
Will the 11,600 psi burst rating of this extension exceed the limits of older 1/8 NPT brass fittings I plan to keep?
The hose bursts at 11,600 psi, far above typical brass-fitting ratings, so the older fittings would fail first; stay within their lower working-pressure limit.
