SKNPM Series Stainless Steel Bulkhead Unions

Features & Key Specifications

Secure Panel Mounting: The threaded body and lock nut allow for secure installation in a panel, creating a stable pass-through point for your tubing, with a secure quick screw connection on both ends rated up to 3.0 MPa (30 bar).

Extreme Environment Performance: Designed to withstand an ultra-wide temperature range of -50°C to 300°C, making it suitable for both cryogenic and high-temperature steam applications.

Superior 316L Stainless Steel: Offers maximum resistance to corrosion from aggressive liquids, steam, and harsh cleaning agents.

Comprehensive Size Options: Available in a full range of metric tube sizes.

Application Fields

Control Cabinets: Creating secure input/output points for pneumatic lines on control panels.

Machine Walls: Routing high-pressure or high-temperature lines cleanly through machine frames.

Process Skids: Providing durable pass-through connections on modular process equipment.

Technical & Selection Guide

A bulkhead union is essential for any professional installation that requires a tube to pass through a wall. The quick screw design of the SKNPM offers a higher level of security than a push-in bulkhead, making it the superior choice for systems with high pressure, vibration, or where connection integrity is paramount.

FAQ

Q: How is this different from a regular union?

A: A regular union (SKNPU) connects tubes in open space. A bulkhead union is specifically designed to be mounted through a hole in a panel or wall.

Q: What size hole do I need to drill in my panel?

A: Please refer to the mounting thread dimension on the product datasheet to determine the correct drill size for your panel.
