Basically, these quick couplings solve annoying problem of wrestling with leaky hose connections under pressrue, especially when you're crawling under a machine with mud in your eyes. 2. Our round head push-pull design lets you snap them on or off in under a second with one hand, and the vacuum-plated surfce treatment means they won't corrode after a season in the field. 3. They're rated up to 5000 PSI comfortably handling the flow rates between 30-50 L/min, but the NBR seals (usually good for -20°C to 120°C) aren't ideal for high-temp oil systems above 130°C — just a heads up there. 4. You'll get them in standerd cartons with both metric and imperial threads avaliable, and we keep about 500 units or so of the common 1/4" and 3/8" sizes in stock right now (confirm lead time for teh oddball specs).
Our standard MOQ is 100 pieces per size, but we can be flexible on mixed sizes for first-time orders.
Yes, we can supply material test certificates for the 304 stainless steel upon request, along with pressure test reports.
We offer metric and imperial threads as standard, but custom thread sizes may be possible depending on volume. Just send us your specs.
For standard sizes with carton packaging, lead time is usually 15-20 working days after order confirmation.
NBR works well with mineral oils and hydraulic fluids up to 120°C, but if you're using phosphate esters or higher temps, we'd recommend switching to a different seal material.

Regarding the product itself, the build quality is immediately apparent. The stainless steel has a substantial, premium feel with a flawless finish, and the machining precision is excellent. All threads are clean and sharp, promising a reliable seal. The push-pull mechanism operates with a satisfyingly smooth and positive action, instilling confidence in its durability under pressure. Customer service deserves special mention for their proactive communication. They provided clear tracking information and followed up to ensure satisfactory receipt. While I have not yet installed these in a system for performance testing, the initial physical inspection and the overall transactional experience have been outstanding. The combination of robust construction, efficient logistics, and attentive support makes this a highly commendable purchase for anyone seeking reliable hydraulic connectors.
