- High price tags – Imported caps from third‑party distributors often carry a 25‑35% markup.
- Inconsistent quality – Dimensional tolerance > ±0.5 mm leads to leaks, re‑work, and warranty claims.
- Long lead times – 6‑8 weeks from order to delivery disrupts just‑in‑time inventory.
- Limited material options – Most suppliers only offer cast iron, restricting corrosion‑resistant designs.
