Redução Einhell R3/8 rosca macho para R1/4 rosca macho conexão de compressor (4139630)

This Einhell thread reducer solves a common compressor setup problem: connecting a tool or hose with R 1/4" female thread to a compressor outlet or manifold with R 3/8" female thread. Instead of buying multiple adapters or replacing fittings, this single brass piece steps the thread size down while keeping a secure, leak-resistant connection. The male-to-male design screws directly into both sides, making it a practical spare for workshops that use Einhell and other standard BSPT-threaded pneumatic equipment.

Highlights

• Reduces R 3/8" male thread to R 1/4" male thread
• Solid brass construction for durability and corrosion resistance
• Compatible with standard BSPT threads used on air compressors and pneumatic tools
• Simple screw-on installation, no special tools required

In daily use

This reducer is a small but essential accessory when your air tool has a smaller inlet than the compressor's outlet. It threads tightly into the female port and provides a clean, tapered seal that holds under typical workshop air pressures. The brass body resists rust and wear, so it remains reliable even in damp or humid environments. Keep one in your compressor kit to avoid downtime when hose or tool threads don't match.
