high pressure pipe fittings are designed for liquid and gas applications

FD-LOK high pressure pipe fittings are designed for liquid and gas applications. The Series Fittings are high pressure NPT fittings for high pressures.
NPT threads must be sealed using a high quality PTFE tape and/or paste product. Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper thread engagement and proper use of thread sealant. NPT pipe fittings is assembled and disassembled because thread deformation during assembly will result in deteriorating seal quality over time. When using only PTFE tape, using thread lubrication to prevent galling of mating parts is recommended.

37° flared tube fittings are the most widely used

37° flared tube fittings are the most widely used fittings in the world.
JIC flared Tube fittings, as defined by the SAE J514, MIL-F-18866 and ISO 8434-2 standards are a type of fitting machined with a 37° flare seating surface. 37° flared JIC tube fittings (such as Parker Triple-Lok) are the most widely used fittings in the world. JIC fitting’s appeal is its adaptability, compact design, ease of assembly, reliability and availability. JIC 37° flare fittings are manufactured in steel, 316 stainless steel or brass, and are readily available through Hose & Fittings, Etc.

Double Ferrule Tube Fittings have been specially designed

double ferrule tube fittings are composed of four precision-engineered components manufactured to very stringent tolerances under rigid quality control procedures. The consistency and quality of these matched components permits the use in many critical applications and severe services.
Double Ferrule Tube Fittings have been specially designed for use in instrumentation, process and control systems of chemical, petroleum, metallurgical, power generation, pulp and paper plants, where fittings are subjected to vibration, high internal pressure, pressure and temperature cycling. Double Ferrule Tube Fittings contains most widely used sizes of Tube fittings but other sizes can also be supplied on demand. The dimensions given in this catalogue are nominal dimensions of fittings in the hand tight position.

Pipe nipples feature leak-tight & permanent connection type construction & are used for high flow, minimal pressure drop & ultra-pure or corrosive chemical applications. high pressure pipe fitting manufacturers provide a proper connection for hydraulic components, and Male and female NPTF threaded fittings in common sizes allow easy connection of all components. high pressure pipes and fittings satisfy the increasing demand for American and European standard pipes and fittings for Plumbing applications.

an excellent pressure fitting

A FD-LOK 37° flared tube fittings is an excellent pressure fitting having a broad selection of styles & shapes and is very extensively used all over the globe. Main features that call for its use are its simplicity, compactness in design, ease of assembly, high reliability, easy availability & global acceptance. These flare tube fittings stainless steel can also be used as hose adapters.
The basic design is simple, which uses a flared tube end to hold & seal the medium under pressure. Main construction consists of three pieces: the body, sleeve & nut. The end of the tube is flared to 74 degrees included angle and held in between the body nose and the sleeve with a nut on top of them, thus resulting in a very effective seal between the fittings and the flared tube.

Double Ferrule Tube Fittings provide leak proof

The double ferrule design and sequential action of the fittings overcome in-variation of tube wall thickness and hardness to assure safe, reliable, leak-free connections. double ferrule tube fittings provide leak proof, torque-free seal at all tubing connections and eliminate costly hazardous leaks in instrumentation and process tubing lines.  Double Ferrule Tube fittings connection uses the compression method for safe connection. It avoids threading, soldering or crimping the tube and permits rapid, easy and reliable connection where removable tubes require perfect tightness, both under pressure and high vacuum as well as under severe temperature and vibration conditions.

Double Ferrule Tube Fittings Design

Double Ferrule Tube fittings have been specially designed for use in instrumentation, process and control systems of chemical, petroleum, metallurgical, power generation, pulp and paper plants, where fittings are subjected to vibration, high internal pressure, pressure and temperature cycling.
double ferrule fittings Design
1. The back ferrule dampens the tube circuit vibration through a spring like action. The back ferrule prevents a carry over of tightening torque from the fitting nut to front ferrule.
2. The front ferrule circumferentially seals the surface between the tube and fitting. The inner taper of front ferrule is pressed on the tube so that a pressure tight impression is formed.
3. Silvering of nut threads prevents seizing/galling. This allows repeated use of fittings.
4. A deep body on tube side and taper guarantees accurate positioning and centering of tube.
