Frequently Asked Questions

What is a MOSMATIC rotary union used for?

A MOSMATIC rotary union transfers fluid from a stationary supply line into rotating machinery. This nickel-plated C38500 brass elbow model with a 3/8 in threaded shaft is used in low-speed industrial applications such as indexing tables, reels, and packaging equipment where a compact, right-angle connection is needed.

What are the specifications of the MOSMATIC rotary union 40.039?

The MOSMATIC rotary union 40.039 is a nickel-plated C38500 brass elbow with 1 passage, a 3/8 in threaded rotating shaft, and a maximum speed of 30 RPM. It is designed for single-flow fluid transfer in tight spaces. For pressure and temperature ratings, consult the manufacturer's datasheet.

Where to buy a MOSMATIC rotary union worldwide?

3G Electric supplies the MOSMATIC rotary union 40.039 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial sourcing partner, we provide genuine MOSMATIC rotating unions and can quote for your specific application requirements.

How to install a MOSMATIC rotary union?

Ensure the rotating shaft threads (3/8 in) are clean and apply thread sealant compatible with the fluid. Support the union to avoid side loads exceeding the bearing capacity. Do not exceed 30 RPM. Verify alignment to prevent premature wear. Always follow MOSMATIC's installation guidelines for torque and flow direction.
