1 Remove the close-up plug.
2 Separate conductors and fill conduit in and around conductors using Killark type “PF” packing
fiber to make a floor dam to hold fluid sealing compound.
Note: Floor dam must be even with the conduit stop in the lower hub of fitting. Exercise care
so as not to damage conductor insulation. Force packing between conductors and hubs,
pushing any shreds of packing fiber away from conductors to prevent leakage path.
3 Use only Killark Type “SC” sealing compound with Killark fittings and do the following:
• Use a clean mixing vessel for every batch of sealant.
• Mix compound at the rate of 3 parts compound to 1 part water by volume.
• Sprinkle compound in water while stirring until thick paste is formed.
Note:Do not mix more compound than can be used in 15 minutes.
• Continue mixing for at least 3 minutes, until consistency is just fluid enough to pour
slowly, like thick gravy (not watery).
4 Slowly pour approved fluid compound into sealing fitting to level of bottom of threads for
close-up plug.
Note: Pour slowly to avoid trapping air bubbles in seal.
5 Immediately wipe off any spilled compound and close seal with the close-up plug.
Note: Initial setting of sealing compound will occur within 30 minutes. Compound requires a
minimum of eight hours above 32 °F to develop sufficient strength to withstand
explosion pressures.
