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 1,000,000+ impulse cycles 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) within 24 hours — 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.
