TYPE
DESCRIPTION
SQUARE BRAIDED NON-ASBESTOSService: A dense but flexible general service packing. It ensures an excellent seal against steam, brine, oil, mild acids, and alkalies. Centrifugal, oscillating and reciprocating shafts, valve plugs and steam.

Construction: Interlock braid using carded synthetic yarns thoroughly impregnated with petroleum based lubricants and graphite finished.

Service Limits: pH range: 4-10—-Temperature: 500°F (260°C)—–Shaft speed: 1575 FPM

TFE IMPREGNATED NON-ASBESTOSService: Excellent multi-service packing for a wide variety of uses throughout a plant. Recommended for use in steam, water, solvents, oils, most chemicals, mild acids and alkalies.

Construction: Interlock braid using carded synthetic yarns thoroughly impregnated with PTFE suspensoid. The finished packing is again coated with PTFE dispersion and a break-in lubricant is added to reduce shaft wear and eliminate glazing at start-up.

Service Limits: pH range: 3-12—–Temperature: 500°F (260°C)—-Shaft speed: 2250 FPM

TALLOW LUBRICATED FLAX PACKING (MARINE GRADE)Service: A medium hard packing which is lubricated throughout. Extremely low frictional characteristics where minimal shaft wear is essential. Rot resistant and ideal for marine use, handling cold water, brine and cold oils. Use in stern tubes, rudder posts and tail shaft liners and industrial applications where minimal shaft scoring rates are required.

Construction: Square plaited construction, paraffin treated and mineral oil lubricated throughout.

Service Limits: pH range: 6-8—-Temperature: 200°F (94°C)—–Shaft speed: 1200 FPM

RAMIE WITH GRAPHITEService: A medium hard packing which is lubricated and graphited throughout. Extremely low frictional characteristics where minimal shaft wear is essential. Rot resistant and ideal for marine use, handling cold water, brine and cold oils.

Construction: Square plaited construction, graphite coated and mineral oil lubricated throughout.

Service Limits: pH range: 6-8—-Temperature: 200°F (94°C)—–Shaft speed: 1200 FPM

PTFE IMPREGNATED FLAXService: For use in stern tube and rudder post stuffing boxes in the marine field. Other applications include certain rotary and reciprocating pumps and valve stems in the paper industry.

Construction: Highest quality ramie yarn with PTFE suspensoid in a square plait construction. Additional break-in lubricant is added to minimize shaft wear and to allow for expansion during the break-in period.

Service Limits: pH range: 5-9—–Temperature: 260°F (126°C)—–Shaft speed: 1575 FPM
