🚀 Critical Transition Connection for Diesel Systems
This straight fitting is an essential transition component, designed to securely join two connections of different specifications in a heating oil line. It allows for the adaptation of a flexible hose or threaded pipe. 3/8'' female (conical) to a tap of 1/4'' female (gas), such as those commonly found in filters or burners.
The precision of its threads, including the end 3/8'' Male Tapered which ensures a perfect seal without additional washers, guarantees a professional and completely airtight installationessential to prevent leaks and maintain system integrity.
✨ EEAT and Benefits: Security Resides in the Connection
Selecting a fitting with the correct taper and gas specifications demonstrates Experience and ensures the Trust in the reliability of the system.
- Upper Seal (Conical Connection): The extreme 3/8'' The tapered male fitting ensures a perfect metal-to-metal seal, eliminating the need for bulky flat gaskets and reducing the risk of leaks due to vibration.
- Essential Compatibility: Ideal for adapting standard diesel fuel hoses (3/8'') to the entrances and exits of 1/4'' in pumps, filters, or deaerators (like the TigerLoop).
- Optimal Flow: Straight design that minimizes pressure losses and turbulence in the fuel flow, ensuring a constant supply to the burner.
- Professional Durability: Made of high-strength material (typically brass) compatible with hydrocarbons and designed to withstand the working pressures in diesel systems.

❓ Frequently Asked Questions (FAQ) Technical
💡 Do I need PTFE (Teflon) or hemp to seal this fitting?
Yes, the connection 1/4'' Male Gas It is a parallel or cylindrical thread that always requires a sealing element (such as PTFE tape or anaerobic diesel fuel sealant) to ensure a watertight seal. The side 3/8'' Male Conical It seals by metal-to-metal contact and sealant should only be used if specified by the manufacturer of the patch cord or receiving component.
💡 What is the difference between a "tapered" thread and a "gas" thread?
The thread Conical (3/8'') It narrows slightly, creating a pressure interference seal between the metal faces of the threads (without the need for a gasket). The thread Gas (1/4'') It is cylindrical or parallel, and the seal is achieved through an external material (PTFE or O-ring) or by contact on the seat, not on the threads.
💡 Can this fitting be used on the high-pressure line of the pump?
This fitting is designed for the low-pressure diesel fuel supply line (typically up to 1 bar (of vacuum or slight positive pressure). It is not designed for high-pressure injection lines downstream of the pump and burner nozzle.
