got a tight spot to route hose. how sharp can i bend this 1/4 CNG hose without kinking it
Answer by: Customer Support on Sep 28, 2025, 1:43 PM
For routing in close quarters, the minimum bend radius on this hose is 2 inches. Keeping your bend at or above that radius helps it hold its shape and perform as intended.
Question by: Wayne J on Oct 28, 2025, 2:04 PM
this hose rated for CNG transfer lines or just the dispenser side of things?
Answer by: Customer Support on Oct 30, 2025, 6:17 AM
Both, actually. The 35NG Series is built specifically for CNG refueling dispensers and CNG transfer lines, so it covers either side of that application. It carries ANSI/IAS NGV 4.2, NFPA 52, and AGA certifications, and it also meets CSA 12.52 standards, which gives it a solid compliance foundation for natural gas fuel service in either role.
