Teflon™ PTFE Balls - Sizes & Materials
APT's high quality PTFE Balls are well suited for industrial applications that require an inert, chemically resistant ball, with the purity, specific gravity and wide operating temperature range of PTFE (polytetrafluoroethylene) that other plastic ball materials don't provide. Applications include PTFE balls used in chemical handling pumps, check valves, ball bearings for light loads, volume displacement balls for chemical baths and many other uses.

PTFE Ball Sizes:
APT manufactures solid Teflon ™ PTFE balls in sizes ranging from 1/8" to 8" diameter.
In stock PTFE Ball sizes vary in availability. It's best to call us at (401) 253-0200 and we'll be happy to let you know if we have the size you need. Large production quantities of our high quality PTFE balls are made-to-order.
Materials:
PTFE Balls can be made-to-order from the following virgin materials and PTFE compounds:
Virgin Grade PTFE
Teflon ™ NXT 85 Modified PTFE
Stainless Steel filled-PTFE (50% 316 Stainless Steel 50% Virgin PTFE)
15% Glass filled-PTFE (15% Glass Fibers compounded with virgin PTFE)
25% Glass filled-PTFE
10% Glass 10% Carbon filled-PTFE (A blend of glass fibers & carbon with virgin PTFE)
Bronze filled-PTFE
Other PTFE material compounds are possible upon request.
PTFE Ball Tolerances and TIR:
Tolerances are dependent on the particular size of PTFE ball. Larger ball diameters are typically specified as /- .005" with a TIR of .005 max. Smaller balls can be held to a tighter tolerance and a TIR of .003 max.
Standard Surface Finishes
Avg. Roughness, Ra, µin
Tumbled: 50 to 63
Machined: 32
Colors & pigments (solid and speckled appearance) are available. Virgin PTFE material is generally white (slightly off white), but color can be custom blended (prior to molding) to aid in part identication or for other ornamental purposes. Colored PTFE generally exhibits the color of the type of filler added. PTFE Compounds with color include white or red glass, molybdenum disulfide (grey), stainless steel (brown), carbon/graphite (black), bronze, etc.. Solid blue and blue speckled are also possible.
