- High Unit Price: Imported caps often carry a 30‑40 % markup due to limited supply chains.
- Inconsistent Quality: Dimensional variance > ±0.2 mm leads to leakage or premature wear.
- Long Lead Times: Typical delivery exceeds 45 days, forcing safety‑stock buildup.
- Limited Material Options: Few vendors offer stainless‑steel or alloy‑grade caps required for aggressive environments.
Fact: A 2025 industry survey of 300 US manufacturers showed that 58 % cite end‑cap failures as a top cause of unplanned downtime.
