Niczuk reduction fitting with external thread M10 to M8, brass

Niczuk reduction fitting with external thread M10 to M8 is a compact brass adapter designed to join components or hoses with different metric thread sizes. The adapter provides a secure mechanical and fluid connection when an external M10 thread needs to be coupled with an M8 threaded part. Its brass construction offers corrosion resistance and dimensional stability suitable for light mechanical, plumbing and instrumentation applications.

Advantages

The brass reduction fitting ensures reliable thread engagement between M10 and M8 interfaces while maintaining a compact profile. Its metal construction resists wear and provides good sealing performance when used with appropriate sealing tape or thread sealant. The adapter is simple to install and requires no special tools beyond common wrenches, making it practical for repair and retrofit tasks.

Suitable for

• Plumbing connections where metric thread sizes differ
• Pneumatic fittings and low-pressure air lines
• Instrumentation and sensor mounting with varying thread sizes
• Repair and retrofit of machines and hydraulic assemblies

Key specifications

• Material: brass
• Connection type: external thread to internal thread adapter (M10 to M8)
• Thread standard: metric threads (M10 and M8)
• Form factor: compact, cylindrical adapter
• Typical applications: fluid and mechanical connections at low to moderate pressure

How to use

Confirm thread directions and sizes before assembly. Clean mating threads of debris and apply appropriate sealing tape or liquid thread sealant if a leak-tight joint is required. Hand-start the threads to ensure proper alignment, then tighten with a suitable wrench until secure; avoid excessive torque to prevent thread or adapter damage. After installation, inspect the joint for leaks under operational conditions.

Usage recommendations

Use the brass reduction fitting in applications within its pressure and temperature limits, avoid exposure to strongly corrosive chemicals, and select compatible thread sealants when used with potable water or sensitive instrumentation to maintain system integrity.
