BT5-5203 Sanden FLX7 Vertical O-Ring Rear Port Fitting Adapter

The BT5-5203 Sanden FLX7 Vertical O-Ring Rear Port Fitting Adapter is used on compatible Sanden compressor applications.
It provides a rear port fitting connection for A/C hose routing.

This adapter uses a vertical O-ring 1″-14 fitting style.
It is designed for use with Sanden FLX7 compressors only.

As a result, it is a useful replacement fitting adapter when the compressor, port layout, and hose routing match the required FLX7 configuration.

Function and Performance

A rear port fitting adapter connects the compressor to the A/C hose connection point.
It helps provide the proper refrigerant port interface between the compressor body and system plumbing.

The BT5-5203 adapter uses a vertical fitting layout.
This layout helps route the A/C line upward from the rear port area when the system design requires that orientation.

Because fitment depends on compressor type, fitting style, port size, and hose routing, compare your current adapter before ordering.

Durability and Design

The BT5-5203 is built for compatible Sanden FLX7 compressor applications.
It should not be treated as a universal Sanden fitting adapter.

The vertical O-ring design uses a 1″-14 fitting style.
Therefore, the compressor port, hose connection, and sealing style must match before installation.

Always verify the compressor model, port location, fitting thread, O-ring style, and hose routing before ordering.

Installation

Install this fitting adapter according to the compressor or A/C system service procedure.
Before installation, confirm the compressor type, rear port layout, fitting style, and O-ring requirements.

Replace seals or O-rings as needed during installation.
Then leak test the A/C system after service.

Do not install this adapter on a compressor model that does not match the Sanden FLX7 requirement.
