RFQ
1. What testing do you perform?
Every hose undergoes pressure, leak, and dimensional tests. We also offer optional pulsation (ISO 6803), burst (4:1 minimum), and material certification testing.
2. Do you provide UHV-compatible hoses?
Our ultra-high vacuum series achieves 10⁻⁸ Torr with special cleaning protocols, all-metal seals, and ASTM A270 compliant surfaces.
3. What's your lead time for custom hoses?
Standard configurations ship in 3-5 days. Custom engineered solutions typically require 2-3 weeks, with expedited 72-hour service available.
4. How do you handle abrasive media?
We offer tungsten carbide (HRC 72) or alumina ceramic (90% Al₂O₃) liners that extend service life 10x in slurry applications versus standard hoses.
