Palmetto Style 1367S – Pure ePTFE (TFE)

Style 1367S (soft) meets specification MIL-P-24396, Type
A (ships). The material is produced from pure, virgin TFE
filament and carefully impregnated before braiding with
a suspensoid of virgin TFE and an inert softener/lubricant
for a secure bond and blocked leakage.
Recommended for rotating service in pumps, mixers,
agitators and kettles, 1367FS is well suited for use with
foods and pharmaceuticals. (See 1367C for an FDA
compliant, heat conductive ePTFE filament packing.)
Style 1367H (hard) meets specification MIL-P-24396,
Type B (ships). For high-pressure, chemical service requiring
a harder material, style 1367H is manufactured in the same
manner as style 1367S without the inert softener/lubricant.
The result is a dense, very firm packing recommended for
use in rotating service as anti-extrusion end rings (with
middle rings of style 1367S) and in reciprocating service
with high pressures and speeds such as in plunger pumps.
The material also provides superior performance in a
wide variety of filter press applications and is the industry
standard for valve stems (not for high pressure steam service).
Order 1367FS for FDA compliant packing.
