Stainless steel high-pressure tube, pre-coned and threaded nipples, and tube support for cone and thread systems rated to 100,000 psi. Supplied from the HIFLUX factory, with lead times quoted up front.
Both connect into the same fittings; the difference is who prepares the ends.
Most first-time buyers should start with nipples and add a tooling set once the system stabilises.
| Tube size (OD × ID) | Rating | Minimum bend radius |
|---|---|---|
| 1/4" (6.35 × 2.77 mm) | 20,000 psi | 1.25" (31.8 mm) |
| 3/8" (9.53 × 5.16 mm) | 20,000 psi | 1.75" (44.5 mm) |
| 9/16" (14.29 × 7.92 mm) | 20,000 psi | 2.63" (66.8 mm) |
| 3/4" (19.05 × 11.13 mm) | 20,000 psi | 3.50" (88.9 mm) |
| 1" (25.4 × 14.27 mm) | 20,000 psi | 4.63" (117.6 mm) |

| 1/4" (6.35 × 2.11 mm) | 60,000 psi | 1.25" (31.8 mm) |
| 3/8" (9.53 × 3.18 mm) | 60,000 psi | 1.75" (44.5 mm) |

Bending tighter than these figures work-hardens the tube at the point of highest stress. Where the route will not allow the radius, use a fitting rather than forcing the bend.
Small-bore tube under cycling or pulsating pressure fatigues at the thread root. Tube support products restrain the run; anti-vibration fitting sets address the joint itself. On a pump or compressor circuit, specify both.
