Merit Brass K414-0804 Pipe Bushing 1/2 X 1/4 in 304 Ss

Product Description

The MERIT BRASS K414-0804 is a threaded pipe bushing designed to reduce a 1/2-inch female port down to a 1/4-inch male connection in piping systems. Constructed from 304 stainless steel, it offers solid corrosion resistance for use in demanding environments. The bushing features a male NPT (MNPT) inlet and a female NPT (FNPT) outlet, connecting via standard threaded engagement. It carries a pressure rating of 150 psi and meets ISO standards at Schedule 40. Plumbers, pipefitters, and mechanical contractors install this type of fitting to adapt pipe or equipment ports to smaller downstream lines.

This bushing is suited for residential and light commercial plumbing, HVAC condensate and refrigerant piping support lines, compressed air systems, and general fluid handling applications where a reduction from 1/2-inch to 1/4-inch NPT thread is required. The 304 stainless steel construction makes it appropriate for mildly corrosive media and wet service environments where carbon steel fittings would be unsuitable.

Key Features

• 1/2 inch MNPT x 1/4 inch FNPT threaded connection for standard pipe reduction
• 304 stainless steel construction for corrosion resistance
• 150 psi pressure rating at Schedule 40
• ISO standard compliant threading
• Compact form factor suitable for tight installation spaces

Compatibility

Designed as an OEM-style replacement or direct-install threaded bushing for any 1/2-inch NPT female port requiring a 1/4-inch NPT male outlet in Schedule 40 piping systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC guidelines. Shut off system pressure and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten; use a pipe wrench with proper backup to avoid cracking fittings or damaging mating threads.
