We’ve handled RFQs for these BSB proportional joint fittings before, and the 0.2MPa opening pressrue is what most thin oil setups need — the flow coefficient sits at 1.8, so it meters consistently.
Built-in one-way valve with a taper spring gives you that sensitive action, but what you don’t see is the copper sleeve coating on the rubber seals that stops them form swelling; that’s why service life holds up longer than typical brass fittings.
Orientation doesn’t matter here — high, low, horizontal — flow stays constant because of teh throttling principle, and the hex head makes welding installation straightforward (galvanized surfce helps with corrosion resistance).
2-4 weeks lead time usually, but our company can confirm once you specify the quantity; MOQ is typically 50 units or so, and we provide COA with each batch.
We typically require a MOQ of 100 pieces per model, but we can be flexible for first-time orders or samples. Just let us know your specific needs.
Yes, our fittings come with ISO 9001 certification and can provide a CE declaration upon request. The materials and galvanized surface treatment meet standard quality checks.
For a standard order, lead time is around 15-20 working days after confirmation. If you need faster delivery, we can expedite with a small surcharge.
Yes, we can adjust the opening pressure to as low as 0.1MPa depending on your thin oil system requirements. Just send us your target specs and we'll confirm feasibility.
Store them in a dry, ventilated area away from moisture and direct sunlight. The galvanized coating protects well, but keeping them in original packaging or sealed containers is best for long-term storage.
Delivery was incredibly prompt and well-handled. The packaging was secure and professional, ensuring the items arrived in perfect condition without any delays. I was thoroughly impressed by the efficiency of the shipping process. Regarding quality, the brass material feels robust and precisely manufactured, meeting the high standards one would expect. The fittings appear durable and reliable for long-term use. Customer service was exceptional; the team was responsive, knowledgeable, and very helpful in addressing my pre-purchase inquiries. They provided clear information and support throughout. Overall, a very satisfactory experience from start to finish. Definitely recommend this supplier for their outstanding logistics, product quality, and excellent service.
My experience with this order was quite positive overall. Regarding logistics, the shipping was prompt and the package arrived well ahead of the estimated delivery window, which was a pleasant surprise. The items were securely packaged with ample protective material, preventing any damage during transit. The tracking information provided was accurate and updated regularly, allowing me to monitor the shipment’s progress with ease. As for the quality, upon inspection, the brass material feels solid and well-machined, meeting the expected standards. The fittings appear precisely manufactured, with clean threads and a good finish, suggesting durability. The service aspect was also satisfactory; communication was clear, and any preliminary questions I had were answered in a timely manner. The overall process from ordering to delivery was smooth and hassle-free. While I cannot comment on the specific performance or technical parameters in use, the initial impressions based on logistics, perceived quality, and customer service are very good. This transaction met my expectations for a reliable purchase.
Yikes, the shipping was incredibly slow and the tracking information was practically non-existent. It took weeks longer than the estimated delivery window, which caused significant delays in our project timeline. Once the items finally arrived, the packaging was subpar and one of the fittings had minor cosmetic damage from what appeared to be rough handling during transit. However, the quality of the brass material itself seems robust and meets the stated DIN standard specifications. The machining appears precise. Customer service was responsive when contacted about the shipping delay, though their initial responses were generic and unhelpful. They did eventually escalate the issue, but the resolution took too long. The overall experience was frustrating due primarily to the logistical failures, overshadowing what seems to be a decent quality product.
Xcellent experience overall! The shipping was incredibly fast and reliable, with my order arriving well ahead of schedule, which was a pleasant surprise. The quality of the items is outstanding; they feel durable and well-made, giving me confidence in their longevity. Customer service was top-notch too—responsive and helpful with any inquiries I had. Highly recommend for anyone seeking efficient and dependable products.
