Heavy Brass 1" Female Adapter

A dependable transition from poly pipe to female-threaded equipment is exactly what the American Granby Heavy Brass 1" Female Adapter provides. Configured as FIPT x insert, it accepts an inserted 1" poly or flexible line on one side and offers a 1" female iron pipe thread on the other, ready to receive a male-threaded nipple, valve, or fitting. It is a foundational connection in countless well and treatment plumbing layouts.

Brass remains a favorite for water connections because it resists corrosion, tolerates the pressures and temperatures of residential and light commercial systems, and threads cleanly without cracking under load. This heavy-pattern adapter is built to those standards, making it a long-lasting choice for well systems, pump piping, pressure tank tie-ins, and treatment equipment manifolds where reliability over many years is the priority.

Where this adapter fits

• 1" FIPT x insert configuration in heavy brass
• Connects 1" poly or flexible pipe to male-threaded components
• Corrosion-resistant brass for long service life in wet environments
• Withstands the pressure and temperature of typical water systems
• Suited to well, pump, pressure tank, and filtration plumbing
• Secure the insert end with a standard stainless pipe clamp

For a leak-free assembly, seat the poly pipe fully onto the barbed insert and clamp it firmly, then seal the threaded side with PTFE tape or pipe dope before mating with the male fitting. Avoid over-tightening, which can deform threads, and check the joint for weeps after the system is pressurized. Whether you are plumbing a new pressure tank, tying in a filter housing, connecting a softener bypass, or repairing an existing line, this 1" female brass adapter delivers the robust, corrosion-resistant transition that pressurized water systems demand, giving installers confidence that the connection will hold for the long haul.

Keeping a few of these female adapters in stock means you are always prepared to tie a poly line into threaded equipment on a moment's notice. Reliable, corrosion-resistant, and built to standard dimensions, it is a small but essential fitting that helps keep well, pump, and treatment plumbing tight, serviceable, and dependable for years. Dependable and corrosion-resistant, it is a fitting installers count on for clean, lasting threaded transitions in water systems.
