Prevost Brass Tapered Nipple

Description

Prevost Brass Tapered Nipple

The Industrial Standard for Rigid Pipe and Tool Connections

The Prevost Brass Tapered Nipple is a precision-machined connector designed to join two female-threaded components or extend an air line port. Featuring high-quality tapered threads (NPT or BSPT), this nipple is engineered to create a wedged, leak-proof seal as it is tightened.

Constructed from heavy-duty brass, it is the ideal choice for connecting air tools, manifolds, and valve blocks where a secure, permanent, and vibration-resistant link is required.

Key Features

• Tapered Thread Geometry: The threads are cut at a precise angle to ensure a “dry seal” connection. As the nipple is threaded into a port, the interference between the threads creates an airtight bond (recommended for use with PTFE tape or thread sealant for maximum security).
• Corrosion-Resistant Brass: Made from premium industrial brass, this fitting is naturally resistant to rust and oxidation. It is suitable for use with compressed air, water, oil, and inert gases.
• High-Pressure Durability: Unlike thin-walled retail fittings, Prevost nipples feature a thick-walled design that handles high-pressure spikes and the mechanical torque of professional installation without cracking.
• Wrench Flats for Easy Install: The center section features a hexagonal or knurled shoulder, providing a solid grip for wrenches. This ensures you can apply the necessary torque for a deep, permanent seal without damaging the threads.
• Superior Temperature Range: Capable of withstanding extreme heat and cold, making it perfect for installation directly onto air compressors where temperatures can fluctuate rapidly.

Common Applications

• Tool Inlets: Extending the air inlet on heavy-duty impact wrenches or grinders to provide better clearance for quick-disconnect plugs.
• Manifold Building: Linking multiple brass tees or blocks together to create a custom air distribution header.
• Component Mounting: Connecting filters, regulators, and lubricators (FRL units) directly to hard-piped systems.
• Drain Ports: Installing moisture drain valves at the bottom of air tank ports.

Selection Guide

Prevost Tapered Nipples are available in various lengths (Close Nipples for tight spaces or Long Nipples for reaching recessed ports) and standard diameters:

• 1/8″ and 1/4″: Standard for small tools, gauges, and sensors.
• 3/8″ and 1/2″: The benchmark for high-flow workshop lines and primary tool inlets.
• 3/4″ and 1″: Designed for main headers and high-volume industrial machinery.
