Hose specification
EN 856 4SH — European Heavy 4-Spiral
EN 856 4SH is the heavy European spiral spec for large bores: roughly 6,090 psi working pressure at -12 stepping to 4,200 psi at -32. It's what big European plant runs on its main circuits.
Working pressure
Ratings by size.
| Size | Working pressure |
|---|---|
| -12 (3/4") | 6,090 psi |
| -16 (1") | 5,510 psi |
| -20 (1-1/4") | 5,075 psi |
| -24 (1-1/2") | 4,715 psi |
| -32 (2") | 4,200 psi |
Working pressures per the published standard with 4:1 minimum burst safety factor. The assembled hose + fitting combination governs the final assembly rating.

EN 856 4SH — European Heavy 4-Spiral — FAQs
4SH vs R13 — which is stronger?
At -12 and -16, 4SH rates higher; at -32 R13's constant 5,000 psi wins. 'Stronger' depends on size — use the charts, not folklore.
Why do foundation rigs eat hoses?
Continuous high-impulse cycling plus abrasion. 4SH construction plus correct routing, sleeving, and clamping is the fix we implement for local foundation companies.
