Legris 3899 04 19 Extended Male Elbow Fitting M5x0.8

Product Description

The LEGRIS 3899 04 19 is a push-to-connect extended male elbow tube fitting designed to connect 4mm outside-diameter tubing to an M5x0.8 metric male thread. Constructed from stainless steel, this fitting handles working pressures up to 435 psi and operates across a temperature range of -4 degrees F to 248 degrees F. The elbow geometry allows a direction change in tight plumbing or pneumatic runs where straight fittings will not fit. Installed by plumbers, pipefitters, and pneumatic system technicians, this fitting suits applications where corrosion resistance and compact routing are both required.

This fitting is suited for use in industrial pneumatic lines, fluid transfer systems, and instrumentation plumbing where metric tubing meets metric-threaded ports. The M5x0.8 male thread end connects directly to corresponding female-threaded ports on valves, manifolds, or equipment panels. The 4mm OD tube entry accepts push-to-connect installation, reducing assembly time compared to compression or ferrule fittings. It is appropriate for both light industrial and food-grade or regulated environments given its broad certification profile.

Key Features

• Stainless steel body for corrosion resistance in demanding fluid and pneumatic applications
• Push-to-connect tube entry for fast, tool-free tube insertion on 4mm OD tubing
• Extended male elbow configuration allows direction changes in tight installation spaces
• Rated to 435 psi maximum working pressure
• Wide service temperature range: -4 degrees F to 248 degrees F
• FKM o-ring seal for compatibility with a broad range of media
• Certified to multiple standards including RoHS, ATEX, PED, ISO 14743, REACH, FDA 21CFR, and USDA NSF H1

Compatibility

Designed for use with 4mm outside-diameter push-to-connect tubing and M5x0.8 metric male-threaded ports in pneumatic and fluid system assemblies.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and isolate the system completely before removing any existing fittings or inserting this fitting into a live line. Ensure the receiving female thread is clean and undamaged before engaging the M5x0.8 male thread end; apply thread sealant appropriate to the media per site or code requirements. When inserting tubing, cut the tube end square and deburr before pushing fully into the collet to ensure a proper seal.
