DOT PUSH IN METRIC UNION 1662: How does this quick connector revolutionize fluid connection technology? "

Revolutionary Connection Technology: Redefining Fluid Connection Standards
The DOT PUSH IN METRIC UNION 1662 series adopts industry-leading patented push to connect connection technology, completely subverting traditional fluid connection methods. The core of this innovative design lies in its unique "plug and play" mechanism, where operators only need to insert the pipeline into the joint to complete the installation without any special tools, greatly improving installation efficiency. The high-precision stainless steel locking ring built into the product adopts a special heat treatment process, which ensures elastic strength while automatically adapting to small differences in pipe diameter, providing long-lasting and reliable mechanical fixation for the connection.
This series of joints adopts a triple sealing guarantee system: the precision machined O-ring is made of chemically resistant fluororubber material, ensuring excellent sealing performance in various media; The innovative conical sealing surface design can generate a self tightening effect when pressure increases; The unique anti pull structure can effectively prevent the pipeline from loosening in a vibrating environment. These three guarantees work together to achieve true zero leakage performance, maintaining perfect sealing even under a working pressure of 1.0 MPa.
This revolutionary connection technology not only simplifies the installation process, but more importantly, solves the common leakage problem of traditional connection methods. Test data shows that after 10000 insertion and extraction tests, its sealing performance can still maintain over 98% of its initial state, which far exceeds industry standards. This improvement in reliability makes the product particularly suitable for industrial scenarios with strict sealing requirements, such as food processing, pharmaceuticals, and other clean environment applications.

Excellent materials and craftsmanship: creating industrial grade durable quality
The DOT PUSH IN METRIC UNION 1662 series has set a new industry benchmark in material selection and manufacturing processes. The main body of the product is made of medical grade 316 stainless steel precision machining. This ultra-low carbon austenitic stainless steel not only has excellent mechanical strength, but also has a molybdenum content of up to 2-3%, giving the product excellent pitting corrosion resistance in chloride environments. Each component is precision machined by a five axis CNC machine, with critical dimensional tolerances controlled within ± 0.01mm to ensure high consistency of batch products.
In terms of surface treatment technology, we adopt a unique triple protection technique: first, micro unevenness is eliminated through electrolytic polishing, then a dense oxide layer is formed through passivation treatment, and finally a nanoscale PVD coating is applied. This composite treatment process enables the surface hardness of the product to reach HV800 or above, and the salt spray resistance test can last for more than 1000 hours without corrosion, perfectly adapting to harsh industrial environments such as humidity, acidity, and alkalinity.
The internal flow channel design also reflects engineering wisdom, using computational fluid dynamics (CFD) optimized tapered and tapered streamlined structures, combined with mirror polishing technology, to reduce pressure loss by up to 40% compared to traditional designs. Specially designed diversion channels can effectively prevent turbulence and ensure smooth fluid flow. The measured pressure drop at a working pressure of 1.0 MPa does not exceed 0.02 MPa. This carefully designed flow channel not only improves system energy efficiency, but also significantly reduces the risk of cavitation and extends the service life of the entire pipeline system.
