Technical sheet

Summary #1

The male/female conical span union, often referred to as a three-piece fitting, is an indispensable junction device for the maintenance and modularity of piping networks. Its unique design allows two sections of a circuit to be disconnected without having to disassemble the entire installation or rotate the tubes. Manufactured according to ISO 4144, this fitting guarantees perfect interchangeability and meets the strictest safety requirements for the transport of pressurized fluids.

Summary#2

Made entirely of AISI 316 stainless steel, this union fitting offers exceptional protection against corrosion and aggressive chemical attack. This high-end stainless steel grade allows for prolonged use in severe thermal conditions, withstanding temperatures ranging from -20°C to +220°C. Its robustness and chemical inertness make it a piece of equipment of choice for the pharmaceutical, food and petrochemical industries, where fluid purity and material durability are paramount.

Summary#3

This model is distinguished by its conical span, which provides a seal by direct metal-to-metal contact without the need for an additional flat seal. This technology limits the risk of leaks due to wear or drying out of traditional polymer seals. Calibrated for a pressure rating of PN 20 bar, the male/female union connection maintains perfect bond integrity, even with frequent pressure fluctuations or mechanical vibrations within the network.6

Summary#4

The connection of this union is designed according to ISO 7-1 (BSPT), combining a tapered male end (R) and a cylindrical female end (Rp). This mixed configuration allows for great installation flexibility, facilitating the connection between a threaded member and a threaded tube. Precision threading ensures smooth screwdriving and increased pull-out strength, allowing for quick integration into pre-existing industrial valves, pumps or manifolds.

Summary#5

Thanks to its rotating nut, the 3-piece male/female union greatly simplifies technical interventions and periodic component replacement. Simply loosen the central nut to release the connection, saving valuable time during maintenance phases. This AISI 316 stainless steel fitting is the ideal investment for installations that require regular modifications, guaranteeing constant reliability over time, whether in water treatment, agriculture or plant maintenance.
