Single Male / Female Stainless 316 Reduction

The simple male/female stainless steel reduction is a strategic transition component, essential for adapting the diameter of your pipes within a complex industrial network. Manufactured with rigorous precision to ISO 4144 standards, this fitting enables you to change from a wider thread to a narrower thread (or vice versa, depending on the direction of flow), while maintaining maximum compactness. Its "simple" or "monobloc" format is particularly appreciated in environments where space is at a premium, as it avoids the accumulation of intermediate nipples and sleeves, thus reducing the risk of potential leaks.

AISI 316 stainless steel: exceptional resistance to corrosive environments

This reduction fitting is machined entirely from AISI 316 (1.4401) stainless steel, a high-end molybdenum-enriched grade offering superior protection against pitting corrosion. This material is specifically chosen for its ability to withstand aggressive chemical agents, acid solutions and extreme saline environments. It has a particularly wide thermal operating range, withstanding temperatures from -20°C to +220°C, making it indispensable for sterilization processes in the food industry, steam circuits or moderate cryogenic transfers.

PN 20 bar performance and concrete applications

With a nominal pressure of PN 20 bar, this reduction ensures maximum operational safety for highly stressed discharge systems and hydraulic circuits. For example, this fitting is used to connect a small-diameter temperature sensor or pressure gauge directly to a larger main manifold. It can also be found in steel mills for cooling circuits, or on agricultural irrigation terminals to adapt the diameter of outlet valves to distribution hoses, guaranteeing a non-deformable connection despite variations in network pressure.

Double ISO 7-1 (BSPT) connection: tapered male and cylindrical female

The connection system scrupulously follows the ISO 7-1 (BSPT) standard, combining a tapered male end (R) with a cylindrical female end (Rp). This conical/cylindrical geometry is the key to perfect sealing: as the threads are screwed together, they mechanically compress to create a hermetic metal-to-metal barrier. For example, when installed on an industrial pump, this threading provides increased resistance to vibration and mechanical micro-movements, preventing the connection from becoming progressively looser over time.

Installation tips for optimized durability

To guarantee a bubble-tight seal and maximum longevity for your 316 stainless steel reducer, we strongly recommend using high-density PTFE tape or a suitable anaerobic resin when fitting on the male part. Its robust design allows repeated assembly and disassembly cycles, making it ideal for industrial maintenance operations or the replacement of instrumentation components. Whether in the pharmaceutical, sugar or water treatment industries, this reduction fitting represents a lasting investment, limiting premature wear and costly interventions on your production lines.
