The Hidden Costs of Unreliable Double Ferrule Fittings

- Premium pricing: USA brands charge 2x more, eroding your ROI on cooling towers and pipelines.
- Supply chain delays: Competitors' poor service means 4-6 week waits, disrupting operations.
- Non-compliance risks: Inferior fittings fail RoHS/CE tests, risking fines in USA markets.
- Vibration failures: 15% of low-end fittings loosen in high-vibe environments like fans and pultruded profiles.
