Why Your Current Tubing End Caps Are Holding You Back
In 2025‑2026, more than 42 % of U.S. manufacturers reported production delays caused by end‑cap failures or excessive procurement costs. You may be experiencing one or more of the following pain points:
- High Unit Price: Imported caps from low‑cost suppliers often carry hidden fees (shipping, customs, quality re‑work).
- Inconsistent Quality: Dimensional tolerance out of ±0.05 mm leads to leaks in hydraulic systems.
- Long Lead Times: Average delivery of 45‑60 days disrupts just‑in‑time (JIT) production schedules.
- Limited Customization: Off‑the‑shelf designs cannot accommodate special thread types or material grades.
- Regulatory Uncertainty: Lack of CE, ISO 9001 or RoHS certifications exposes you to compliance risk.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom weld on tubing end caps?
Our standard MOQ is 5,000 pieces, but we can accommodate pilot runs as low as 1,000 units with a small tooling surcharge.
Can you provide material certifications for stainless‑steel caps?
Yes. Each batch is accompanied by a Mill Test Report (MTR) and CE‑type declaration confirming compliance with ASTM A240.
How long does shipping take to the United States?
Standard air freight delivers within 7‑10 business days; sea freight is 25‑30 days. We handle customs clearance to minimize delays.
Do you offer a money‑back guarantee if the caps fail dimensional inspection?
Yes. We provide a 30‑day replacement guarantee at no extra cost, provided the failure is due to our manufacturing tolerance.
What payment terms are accepted for first‑time buyers?
We accept T/T (30 % deposit, 70 % before shipment) or L/C at sight. For qualified accounts, net‑30 terms can be arranged.
