Comparison
EN 856 4SP vs EN 856 4SH
Both are European four-spiral hoses; 4SH is the heavier spec — at -12 it rates roughly 6,090 psi versus 4SP's 4,050 psi. Laylines decide: replace 4SH with 4SH. Where a circuit sits within 4SP's rating, the lighter hose routes more easily and costs less.

- Anything the OEM plumbed with 4SH
What happens if you mix them
Substituting 4SP where 4SH was specified strips the safety factor from a 6,000 psi-class circuit. Read the layline of the failed hose — then match or exceed it.
4SP vs 4SH Spiral Hose — FAQs
The layline is worn off — how do you identify my spiral hose?
By OD, bore, ply count on the cut end, and the machine's circuit spec. When in doubt we build to the higher rating.
