Hose specification

SAE 100R15 — 6,000 PSI Constant

SAE 100R15 is the 6,000 psi constant-working-pressure spiral hose — the specification modern high-tonnage excavators and high-pressure systems are plumbed with. Every size carries the full 6,000 psi rating with a 4:1 safety factor.

SAE 100R15 — 6,000 PSI Constant — FAQs

Is R15 overkill for my machine?

If the circuit spec sheet says 5,000+ psi working pressure or the OEM plumbed it with R15/4SH, no. Downgrading high-pressure mains to save a few dollars is how hoses become shrapnel.

What fittings go on R15?

Heavy interlock ends — commonly code 62 flange heads, heavy ORFS, and DKOS metric. We stock and crimp all three.
