Choosing the wrong packing can cause leakage, shaft wear, or premature failure. Our application engineers help B2B buyers match the packing to the equipment and operating conditions — not just to a product name.
Enough to cross-reference the gland or stuffing box specification.
Determines the packing cross-section size.
Peak excursions often decide fiber selection.
Selects density, braid structure, and reinforcement.
Drives impregnation and chemical compatibility.
API 6A, NACE MR0175, or other project specs.
Response time after you send the equipment and operating details.
Recommended fiber type and impregnation matched to the operating conditions.
Cross-section size and braid structure confirmed against your equipment.
If the equipment is legacy or discontinued, send a drawing or measurement and we will reverse-match a suitable packing.
High-temperature steam, up to 300 °C
→Aramid fiber packing or graphite PTFE packing
Chemical media, pH 2–12
→PTFE packing with aramid corners or graphite PTFE
High-pressure valve, 20 MPa
→Graphite PTFE packing or die-formed graphite ring
Abrasive slurry
→Aramid fiber packing with abrasion-resistant impregnation
Provide the valve or pump make and model, stem or shaft diameter, continuous and peak operating temperature, operating pressure, media and pH range, and any certification requirement such as API 6A or NACE MR0175. These six inputs let our engineers recommend fiber type, impregnation, cross-section size, and braid structure in one pass.
Recommendations are returned within one business day after you send the equipment and operating details. For routine configurations the reply includes fiber type, impregnation, cross-section size, and braid structure; for non-standard cases we may ask one follow-up question before confirming.
Yes. For legacy or discontinued equipment, send a drawing, a photo of the stuffing box, or the measured stem or shaft diameter and gland dimensions. Our engineers reverse-match a suitable packing from the available measurements rather than relying on the original model number.
Yes. For high-pressure valve service around 20 MPa, we typically recommend graphite PTFE packing or die-formed graphite rings. For sour service, NACE MR0175 material selection support is available and the recommended packing is confirmed against the media and pH range before quotation.
Include the model, stem/shaft size, temperature, pressure, and media. We will reply with a recommended packing and a quote.
