The Optibelt 25 / 14M 4004 AFX is an Alpha Flex timing belt in the HTD 14M profile with a 4004 mm length. This page covers how to match it to the belt you are replacing. We carry this belt for maintenance, engineering and purchasing teams in the US, Canada, Mexico and South America.
Start with the marking on the back of the old belt. The 25 / 14M 4004 AFX code tells you the profile and the length: HTD 14M and 4004 mm. The 14 mm pitch is the distance between tooth centers, so a 14M belt will not run correctly on a pulley cut for another pitch. Compare the full code, not just the length, before you order.
If the back of the belt is worn or the marking is gone, measure the old belt and check the drive. Count the teeth if you can, confirm the width, and note the pulley grooves. A belt that has run for years may sit slightly stretched, so use the printed code as the primary reference and the measurements as a check.
Send the part number 25 / 14M 4004 AFX by WhatsApp or email and our team will confirm it. If you are unsure between this belt and another, include a photo of the old belt marking and the drive. We reply promptly and can help you confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I confirm the 25 / 14M 4004 AFX is the belt I need?
- Read the code on the back of the belt you are replacing. Match the profile HTD 14M and the 4004 mm length. If the marking is unreadable, measure the old belt and check the pulley grooves before ordering.
- What does the 14M profile mean for fit?
- HTD 14M is the profile, and 14 mm is the pitch. The pitch must match the pulley grooves. A belt with a different pitch will not seat correctly even if the length looks close.
- What should I send to get a quote?
- Send the part number 25 / 14M 4004 AFX by WhatsApp or email. If you want us to double-check it, include a photo of the old belt marking and the drive where it runs.
