3/8″ x 1/2″ Reducing Barrel Nipple

Precision Engineering for Seamless Transitions

The 3/8″ 3/8″ x 1/2″ Reducing Barrel Nipple is an essential “reducing” fitting designed to connect two female-threaded pipes or components of different diameters. Unlike “close nipples” which are threaded end-to-end, the barrel design includes a center section of unthreaded tube. This extra length provides better grip during installation and allows for precise spacing between components in complex plumbing manifolds.

Key Features & Benefits:

• Dual-Diameter Reduction: Perfectly bridges 3/8″ and 1/2″ lines, eliminating the need for bulky multi-fitting adapters.

• Superior Material Quality: Manufactured from 100% Genuine Brass or Industrial-Grade Stainless Steel, ensuring the fitting will not rust, flake, or contaminate potable water supplies.

• High-Pressure Reliability: Rated for standard residential and commercial pressures up to 16 Bar (approx. 232 PSI), making it suitable for both municipal water lines and pumped filtration systems.

• Thermal Versatility: Designed to operate safely in temperatures ranging from -20°C to 120°C, ideal for hot water geysers and steam-based industrial processes.

• Standardized Threading: Features precision-cut NPT or BSPT tapered threads to form a secure, water-tight seal when used with PTFE (Teflon) tape or pipe sealant.

Typical Applications in Sri Lanka:

• Water Purifier Installations: Connecting 1/2″ main water inlets to 3/8″ feed lines for high-flow RO systems or under-sink filters.

• Sanitary Fittings: Adapting bathroom shower valves, bidet sprays, and kitchen mixer taps where pipe sizes differ.

• Industrial Maintenance: Used in chemical processing, air compressors, and pneumatic systems where 3/8″ and 1/2″ ports must be joined.

• Gas Line Transitions: Suitable for low-pressure gas cooking equipment and industrial gas handling.
