Specifications for Low Pressure Tubing
Useful for HPLC & Other Applications PFA Tubing (PerFlourAlkoxy)
All of MicroSolv PFA capillaries are extruded from virgin PFA manufactured exclusively by Dupont. We do not add any additives to the original PTFE material, except for color particles in the solid colored tubing.

PFA tubing and capillaries do not contain micro-pores in the tubing wall to the same extend as PTFE tubing.

MTC Cat No. Description Pressure (bar/psi)
48310-20 Tubing, PFA, 1/16" OD x 0.50 mm ID 100 / 1450
48310-30 Tubing, PFA, 1/16" OD x 0.75 mm ID 75 / 1075
48310-40 Tubing, PFA, 1/16" OD x 1.00 mm ID 55 / 800
48335-65 Tubing, PFA, 1/8" OD x 1/16" ID 75 / 1075

Tolerances for PFA tubing and
capillaries is as follows:

up to 2.0 mm: +/- 0.05 mm
2.0 mm and above: +/- 0.10 mm
Tensile Strength: 4,000 psi
Compressive Strength: N/A
Durometer (Hardness): D-60
Melting Point: 575°F
Refractive Index: 1.35



FEP Tubing (FlourinatedEthylenePropylene)
All of MicroSolv FEP low pressure tubing is extruded from virgin FEP. FEP is especially useful in ion-chromatography applications. Do not use FEP above 80C.

MTC Cat No. Description Pressure (bar/psi)
48410-20 Tubing, FEP, 1/16" OD x 0.50 mm ID 95 / 1375
48410-30 Tubing, FEP, 1/16" OD x 0.75 mm ID 75 / 1075
48410-40 Tubing, FEP, 1/16" OD x 1.00 mm ID 50 / 725
48445-65 Tubing, FEP, 1/8" OD x 1/16" ID 70 / 1000

Tolerances for FEP tubing and
capillaries is as follows:

up to 2.0 mm: +/- 0.05 mm
2.0 mm and above: +/- 0.10 mm
Tensile Strength: 3,500 psi
Compressive Strength: 2,200 psi
Durometer (Hardness): D-55
Melting Point: 500°F
Refractive Index: 1.338



ETFE Tubing (TEFZEL)
All of MicroSolv ETFE tubing is extruded from virgin ETFE. We do not add any additives to the original ETFE material. ETFE tubing is widely used in all low- and medium pressure laboratory applications due to the relatively high burst-pressure. Please be aware that ETFE tubing is not resistant to all chemicals. Some organic solvents may cause swelling and reduce the pressure stability.

MTC Cat No. Description Pressure (bar/psi)
48510-20 Tubing, ETFE, 1/16" OD x 0.50 mm ID 150 / 2175
48510-30 Tubing, ETFE, 1/16" OD x 0.75 mm ID 115 / 1625
48510-40 Tubing, ETFE, 1/16" OD x 1.00 mm ID 85 / 1225
48555-65 Tubing, ETFE, 1/8" OD x 1/16" ID 110 / 1600

Tolerances for ETFE tubing and
capillaries is as follows:

up to 2.0 mm: +/- 0.05 mm
2.0 mm and above: +/- 0.10 mm
Tensile Strength: 7,500 psi
Compressive Strength: 7,100 psi
Durometer (Hardness): D-75
Melting Point: 490°F
Refractive Index: 1.40



PTFE Tubing (PolyTetraFlourEthylene)
PTFE tubing is widely used in all low-pressure laboratory applications. Please be aware that all PTFE tubing does contain micro-pores in the tubing wall. These micro-pores allow a quick air exchange. This is of special consideration for degassed and oxygen-sensitive solvents.

All MicroSolv PTFE tubing is extruded from virgin PTFE manufactured exclusively by Dupont, the original manufacturer of PTFE material. We do not add any additives to the original PTFE material, except for color particles in the solid colored tubing.

MTC Cat No. Description Pressure (bar/psi)
49210-10 Tubing, PTFE, 1/16" OD x 0.25 mm ID 55 / 800
49210-20 Tubing, PTFE, 1/16" OD x 0.50 mm ID 50 / 725
49210-30 Tubing, PTFE, 1/16" OD x 0.75 mm ID 35 / 510
49210-40 Tubing, PTFE, 1/16" OD x 1.00 mm ID 25 / 365
49225-65 Tubing, PTFE, 1/8" OD x 1/16" ID 35 / 510
49225-100 Tubing, PTFE, 1/8" OD x 2.40 mm ID 20 / 290

Tolerances for PTFE tubing and
capillaries is as follows:

up to 2.0 mm: +/- 0.10 mm
2.0 mm and above: +/- 0.20 mm
Tensile Strength: 3,000 psi
Compressive Strength: 3,500 psi
Durometer (Hardness): D-50
Melting Point: 635°F
Refractive Index: 1.35

Note: The data collected in column ’Pressure’ show the recommended permanent maximum working pressure at room temperature for non-destructive solvents. Change of solvents and temperature may result in lowered mechanical stability. Keep in mind that tight bends of the tubing, use of wrong tools for cutting and bad connections may result in mechanical damage to the tube and by this reduce the pressure stability.
