Radiator Valve End Cap – Precision‑Engineered for Reliable Heat Transfer
Designed for industrial HVAC, power‑plant, and marine applications, our radiator valve end caps eliminate leaks, reduce maintenance, and boost system efficiency.
Why Your Current Radiator Valve End Caps Are Holding You Back
- High Unit Cost: Imported caps from limited suppliers can cost up to 35% more than a domestic OEM source.
- Frequent Leak Failures: Inferior casting tolerances cause mis‑alignment, leading to average downtime of 4 hours per incident.
- Long Lead Times: Traditional manufacturers need 45‑60 days to ship, disrupting just‑in‑time production schedules.
- Regulatory Non‑Compliance: Missing CE, RoHS, or ISO‑9001 certifications can halt projects in EU or US markets.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom radiator valve end caps?
Our standard MOQ is 500 pcs. For larger projects we can lower the MOQ to 200 pcs with a short‑run die‑casting process.
Can you provide CE and RoHS certification for each batch?
Yes. Every shipment includes a Certificate of Conformity (CoC) and a RoHS test report signed by an SGS auditor.
Do you offer sample testing before full production?
We provide a free 5‑unit sample (shipping cost covered by you) with full dimensional and pressure testing. If the sample meets your specs, we proceed to mass production.
What are the payment terms for US buyers?
Typically 30% T/T in advance, 70% against B/L copy. For long‑term partners we can arrange L/C at sight or net‑30 after the first order.
How do you handle after‑sales warranty?
All caps come with a 12‑month warranty against material defects. Defective units are replaced within 7 days of claim receipt.
