Marigold 344BIL Packing is a low friction packing manufactured from 100% pure PTFE filament that has been thoroughly impregnated with a PTFE suspensoidal blocking agent and a proprietary break in lubricant.
This soft but dense compression packing is easily conformable and offers very low friction during both start-up and operation. Commonly used in valve applications, Marigold 344BIL Packing is particularly well suited to environments that require a low friction packing capable of withstanding attack from chemicals anywhere on the 0-14 pH scale.
A variant on our Marigold 344, Marigold 344BIL Packing is also utilised in temperatures up to 260ºC with a pressure rating of up to 20 BAR. The presence of the break-in lubricant in 344BIL does allow this grade (and 344BIL-SC) to withstand higher shaft speeds than the pure PTFE Marigold 344 (8 MPS compared to 5 MPS).
Marigold 344BIL Packing is available from AG in standard sizes ranging from 3.2mm² to 25.4mm², though special sizes and custom sized packing rings can also be produced upon request.
AG also offers four similar interlock braided packings. These include our Marigold 344BIL-SC (lubricant & silicone core), 344-SC (silicone core), 344FDA (utilised in food applications), and the aforementioned Marigold 344. For more information on these, or any other packing in our comprehensive Marigold range, please do not hesitate to contact your local AG branch.
