Pigtails

For over 20 years, the Flexibile Components brand of Saint-Gobain Performance Plastics has been the widely acknowledged industry leader in the engineering, manufacture, sales and support of compressed gas and cryogenic hoses. As an active member of six CGA committees, we have played an important role in developing the industry's safety, technological, training and educational standards.

Non-Metallic and Metallic Pigtail Products

Value pricing, extreme flexibility and long-lasting characteristics make non-metallic core pigtails the most widely specified hose assemblies. Our large variety of end fittings, safety and productivity options allow you to select the hose best suited to your application.

 

Non-Metallic Core Pigtails

PTFE Chemfluor Core, Stainless Steel Braid
Ideal for a wide range of industrial applications, PTFE Chemfluor is non-porous, chemically inert and requires zero maintenance. PTFE is an FDA approved material. When coupled with the Oxy-Flex® end fitting and cleaned for oxygen use, high temperature capabilities make PTFE the best choice for medical or industrial oxygen filling. Flexible Components PTFE is up to 30% thicker than competitive products for greater flexibility, kink resistance, longer life and less permeation.

• PTFE core, single SS braid. Style 4TS-3000 psi
• PTFE core, double SS braid. Style 4TD-3600 psi with brass end fittings
• PTFE core double SS braid. Style 4TD-4500 psi with SS end fittings
• PTFE core, high density SS braid. Style 4TH-5000 psi
• PTFE core, double SS braid, double SS spiral wrap. Style 4TX-6000 psi 

 

ETFE Tefzel® Core, Stainless Steel Braid

Tefzel pigtails are widely specified for use in hydrogen and helium service. Tefzel has a permeation rate approximately 77% lower than PTFE.

• ETFE core, single SS braid. Style 4TZ-3000 psi
• ETFE core, double SS braid. Style 4TZD-3600 psi with brass end fittings.
• ETFE core, single SS braid. Style 4TZD-4500 psi with SS end fittings.

 

Synflex® Nylon Core, Polyurethane Outer Jacket

A low cost alternative for nitrogen, argon and helium pigtails only. Available with carbon steel fittings.

• Nylon core, polyurethane cover. Style 3130-3000 psi
• Polyester core, polyurethane cover, cold temp flexibility. Style 3160-3000 psi
• Nylon core, polyurethane cover. Style 3R80-5000 psi

Non-Metallic Core Pigtail Cross Sections

Metallic Core Pigtails

Many applications require a metal "bellows" type hose which provides an all welded, flexible alternative to rigid pipe and tubing with zero permeation even at high pressures and cryogenic temperatures. A variety of alloys, safety features and options are available so that an assembly matching your precise needs can be provided. All hose assemblies are constructed with heavy-gauge end fittings. Maximum allowable working pressure and date of manufacture are permanently marked on each assembly.

Stainless Steel Inner, Stainless Steel Braid

316 SS pigtails are designed for strong, safe and flexible operation in demanding specialty gas environments. Zero permeation characteristics do not allow gas or atmosphere to pass through its wall in either pressure or vacuum applications. Ideal for flammable, toxic, high purity and small molecule gases.

• SS core, double SS braid. Style 4MDS6-3850 psi
• SS core, double SS braid. Style 4MDHP-4800 psi

 

Monel® Inner, Monel Braid

Specifiy Monel pigtails when 316 SS inner is not compatible with a corrosive gas such as hydrochloric acid.

• Monel core, double Monel braid. Style 4MDM-3000 psi
• Available with Monel fittings.

Monel® Inner, Stainless Steel Braid

Monel pigtails with SS braid are ideal for oxygen service where particle impingement failure is a concern. The SS braid is more economical and allows higher working pressures than Monel braid.

• Monel core, double SS braid. Style 4MDMS-4200 psi
• Available with Monel or SS fittings.
   

 

A:  316L SS TIG weld Argon purged B:  316L SS corrugated inner core.  Very close pitch for extreme flexibility, high flow and longer hose life -- 20 convolutions/inch 2X the industry standard C:  316L SS end fitting D:  One piece 304 SS weld and casing crimp ferrule for superior connection to armor casing.  Reduces stress at weld joint. E:  Double layer of 304 SS braid -- 3850 psi working pressure  F:  Monel TIG weld Argon purged G:  Monel 400 series inner core and double braid -- 20 convolutions/inch for extreme flexibility and up to twice the hose life.  3000 psi working pressure H:  Monel end fitting for superior corrosion resistance I:  Smooth transition from hose to fitting J:  One piece extra long weld and casing collar eliminates stress at end fitting K:  304 SS interlocked armor casing fully protects hose
