Coupler Specifications

The Banjo 125F is a Type F cam and groove coupler built from polypropylene with an EPDM gasket. It connects a 1 inch coupler to a 1-1/4 inch MNPT thread. The fitting handles a maximum working pressure of 300 psi at 70 degrees Fahrenheit.

Installation Requirements

This coupler needs a matching 1 inch Type F adapter and a female NPT port for the 1-1/4 inch male thread. It frees the installer from using separate bushings or reducers to bridge the size difference. No locking arm is included so a separate safety clip or pin may be required for vibration-prone lines.

Ideal Use Cases

The 125F suits plumbing and fluid-transfer systems that join 1 inch hose or pipe to 1-1/4 inch NPT equipment using quick-disconnect cam arms. Buyers needing a built-in locking arm, a different body material such as stainless steel, or a coupler sized for other thread standards should look at alternative fittings.

Questions about this item

What is the maximum working pressure at 70 F for the 125F coupler?

The Banjo 125F coupler is rated for a maximum working pressure of 300 psi at 70 F.

How much heat can the polypropylene body handle during continuous operation?

The polypropylene body is rated for use at 70 F; sustained temperatures above this level will reduce the 300 psi pressure rating.

What thread size must the mating fitting have to connect to the 1-1/4 in MNPT end?

The male NPT end uses a 1 1/4 in - 11 1/2 thread, so the mating part must match that thread specification.
