This Moldable Packing is used to stop leaking, worn propeller and rudder shafts, where packing alone doesn't make a good seal. The Drip Less Moldable Packing Kit contains Teflon® moldable packing and Teflon® paste. This combination of materials forms a self-lubricating dripless seal within the leaky packing box - keeping the water out. Standard shaft packing (sold separately) is used as a retainer to hold the moldable packing in place in the stuffing box. We recommend using Graphtex Ultra (GTU) as the packing since it doesn't shrink over time.

In use, several rings of the moldable packing are sandwiched between two rings of standard packing. Some higher speed shafts may exceed the performance limits of the kit, so be sure to compute the formula shown below for your particular application:


  • Will pack up to a 1 1/2" shaft
  • Shaft diameter (in inches) x maximum shaft (not engine!) rotation x 0.25 = ?
  • The answer must not exceed 900, and usually does not
    • If it exceeds 900, the shaft rotates too fast to use this product
    • In that case, use the self-lubricating Graphtex Ultra (GTU) packing, which is ideal for high speed applications
  • Remember, you need to purchase standard packing for use with this kit

What is the max temperature of this product. Need to know as not to over tighten . At inital startup packing box rises to about 140 … what is normal. Hesitant to tighten the packing gland to stop drips at this temp. Going slowly to set GTU at both ends.

Sorry we do not have that answer, but here is a link to the Mfg's website, perhaps you can find what you are looking for there.
