 Ham-Lets stainless steel high pressure range of 37º (37 degree) flare fittings are all manufactured to meet SAE J514 Standards.
Tube flaring is considered to be a type of forging operation and is usually a cold working procedure. During assembly, a flare nut is used to secure the flared tubing's tapered end to the also tapered fitting, producing a pressure-resistant, leak-tight seal. Flared connections offer a high degree of long-term reliability and for this reason are often used in mission-critical and inaccessible locations.

FTI offer a full range of other valves from Ham-Lets extensive range, covering:
•H400 Check Valves
•H911 Industrial Excess Flow Valves
•H900 Relief Valves
•H900 HP Relief Valves
The H400 series is a compact designed check valve which provides an accurate operating point. H400 valves are normally closed. When a differential pressure between inlet and outlet is higher than the set pressure of the spring, the loaded poppet will move backwards and will enable a free passage of flow through the valve.
 The H911 excess flow valve series is a normally open valve when the system is balanced. If the system becomes unbalanced and the downstream pressure drops the valve seals. If the downstream pressure increases the ventilation outlet (“bleeding”) enables the system to balance the pressures and the valve reverts back to normally open. They offer excellent automatic shut off in a wide range of potentially dangerous environments in fuel systems, toxic media etc, etc.
The H900 series is a relief valve for low pressure service. The valve is normally closed it will open when system pressure reaches the set level. It will re-close when the pressure system falls below the set level. The H900 has service levels adjustable from 10-225 psi.
The H900HP is a high pressure version of the H900 described above – they have a set pressure range from 50 psig to 6000 psig.
 The H600 filter series is available in brass or stainless steel. They are available as in-line or for easy maintenance as T-Type filters. They can operate in pressures of up to 6000 psi and are available in various ends. They have a range of sintered filters fom 0.5 to 90 micron and strainers in 140, 230 and 440 microns.
