T-Lon is now offering a line of PTFE spiral back-ups. We are making available the three most popular spiral ring series of 28782, 28783, and the TF171 series. These will compliment our popular standard split and solid backups in 28774, 27595 series and the metric "G" & "P" style J.I.S. standards backups.
These back-ups meet industrial standards, not the MS Standards. These parts are traceable by lot number, material batch, and date of manufacture. T-Lon Products, Inc. can certify the typical properties of elongation, tensile strength, specific gravity, and material composition as needed.
We believe you will find our pricing on this newest addition to the T-Lon family of back-up rings to be very attractive.
