Frequently Asked Questions
My coupler keeps splitting / leaking — is that normal?
No. Body splitting and leakage are usually caused by weak materials or worn bearing grooves. Our couplers pass rigorous impulse life cycle and burst pressure tests. Send us a photo of the failed part and we will tell you the root cause.
I don't know the thread size — M21, BSPP or NPT?
Send us a photo with a ruler next to the thread, or the part number. We identify the spec and the interchangeable brand (Faster, CEJN, Stucchi, Dixon) — free of charge.
Do you have Kubota / Bobcat / John Deere replacements?
Yes. We cover 46mm and 48mm body flat face styles, JD-style and Bobcat-style couplers, plus Kubota-specific parts — at a fraction of OEM pricing.
What is the MOQ?
For standard products, MOQ is confirmed during quotation. For OEM custom couplers, typical MOQ is 5,000 units depending on design complexity. Sample orders are available before bulk production.
What is the lead time?
Standard products ship fast from our $5M inventory. For OEM custom couplers, design and prototype development typically takes 6 weeks, with lead times confirmed during planning.
How do you guarantee quality?
Every batch passes 10+ tests in our lab (impulse, burst pressure, salt spray, leakage, interchangeability etc.).
