Valve Stem Packing 20 ft

Anti-Seize 19093 is a PTFE valve stem packing supplied in a 20 ft length. It is designed for sealing valve stems in pumps and valves across industrial and plumbing systems. The material handles a pH range from 0 to 14 and carries FDA approval. It operates reliably in extreme temperatures from -400 °F to 500 °F.

Replaces worn gland packing

Existing packing that leaks or degrades under chemical attack or thermal cycling is the target for replacement. The jump is worth it when the service demands full pH resistance and a 500 psi pressure rating for both pumps and valves. The PTFE construction resists cold flow and maintains seal integrity where softer materials extrude or carbonise.

Suits maintenance teams sealing rotating

Engineers specifying packing for high-purity or corrosive media will benefit from the FDA-compliant PTFE. It is not for applications exceeding 500 psi or 500 °F in steam service. Buyers needing pre-cut rings or a specific cross-section other than 3/32 sq in should look at alternative packing formats.

Questions about this item

What size packing seal does the 19093 valve stem packing use?

The packing seal size is 3/32 square inch, so the gland or stuffing box must accommodate that cross-section for a proper fit.

How do I install the 20 ft roll of PTFE valve stem packing, and what step is often missed?

Cut the required length, wrap it around the stem, and compress it evenly with the gland follower; the step often missed is seating each ring individually before final tightening.

When should the PTFE valve stem packing be replaced?

Replace the packing when leakage appears at the gland, the stem shows scoring, or after exposure beyond the 500 °F or 500 psi limits.
