Merit Brass K612-3208 Pipe Reducer 316 Ss Fnpt 150 Psi

Product Description

The MERIT BRASS K612-3208 is a threaded pipe reducer fitting designed to transition from a 2-inch line down to a 1/2-inch line in piping systems handling fluids or gases. Constructed from 316 stainless steel, it resists corrosion in demanding environments including chemical exposure and marine or coastal installations. The fitting uses female NPT (FNPT) connections on both ends for straightforward threaded assembly and carries a 150 psi pressure rating. At 2-7/32 inches in length and 0.85 pounds, it is a compact, solid-metal component suited for professional plumbing, process piping, and industrial service work.

This reducer is appropriate for residential and commercial plumbing applications where a significant pipe size reduction is required inline. The 316 stainless steel construction makes it a strong choice for corrosive fluid systems, food-service piping, marine plumbing, and chemical process lines. Licensed plumbers and pipefitters commonly install this fitting in both new construction and retrofit scenarios where standard threaded iron or stainless piping systems are in use.

Key Features

• 316 stainless steel construction for superior corrosion resistance compared to 304 grade
• FNPT x FNPT end connections for standard threaded pipe assembly
• 150 psi pressure rating for low-pressure piping service
• 2 x 1/2 inch reducing size handles significant diameter transitions in a single fitting
• ISO standard compliance for dimensional consistency
• Compact 2-7/32 inch body length minimizes required clearance in tight installations

Compatibility

Designed as an OEM-style threaded replacement or new-installation fitting for 2-inch to 1/2-inch FNPT stainless steel piping systems rated at 150 psi or below.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads being engaged, following the sealant manufacturer's instructions for stainless steel fittings. Do not over-tighten threaded stainless fittings, as galling of the threads can occur.
