Cable grom­mets for sub­sequent in­stall­a­tion



  • Eas­ily cre­ate se­cure seals around cables that are already in place
  • Ex­tremely flex­ible and elast­ic
  • Quick and easy in­stall­a­tion
  • Wa­ter­proof, also suit­able for pen­et­ra­tions in façades and roof lin­ings
  • Air­tight bonds ac­cord­ing to DIN 4108-7, SIA 180 and OENORM B 8110-2
  • Low­est VOC rat­ing in haz­ard­ous sub­stance test


The seal­ing grom­mets, pro clima KAFLEX post, are used for the quick and long-term, se­cure air­tight in­stall­a­tion of pre-in­stalled cables in ac­cord­ance with DIN 4108-7. As a res­ult of the wa­ter­proof ad­hes­ive and car­ri­er ma­ter­i­als, KAFLEX post is also suit­able for out­door use (e.g. wind­proof­ing in the roof lin­ing and façade).

Be­fore stick­ing, sub­sur­faces should be brushed off, wiped clean with a cloth or cleaned us­ing com­pressed air.
Ad­he­sion to frozen sur­faces is not pos­sible. There must be no wa­ter-re­pel­lent sub­stances (e.g. grease or sil­ic­one) on ma­ter­i­als to be bon­ded. Sub­sur­faces must be suf­fi­ciently dry and have suf­fi­cient load-bear­ing ca­pa­city.

In­stall the cables without strain, fix cables with a cable clip as re­quired.

A per­man­ent bond is achieved on all pro clima in­door and out­door mem­branes, oth­er va­pour re­tarder and air­tight­ness mem­branes (e.g. PE, PA, PP and alu­mini­um foil) as well as roof and wall lin­ing mem­branes (e.g. PP and PET).
Ad­he­sion and joints can be car­ried out on planed and painted wood, hard plastics and met­al (e.g. pipes, win­dows etc.), hard wood-based pan­els (chip­board, OSB and ply­wood pan­els, MDF board and soft­wood fibre sub-roof pan­els).
Wood fibre sub-roof pan­els and smooth min­er­al sub­sur­faces re­quire pre-treat­ment with TESCON PRIMER be­fore bond­ing. Con­crete or plaster sub­sur­faces must not be sandy or crum­bling.

The best res­ults in terms of struc­tur­al sta­bil­ity are achieved on high-qual­ity sub­sur­faces.
It is your re­spons­ib­il­ity to check the suit­ab­il­ity of the sub­sur­face; ad­he­sion tests are re­com­men­ded in cer­tain cases.
Pre­treat­ment with TESCON PRIMER is re­com­men­ded in the case of sub­sur­faces with in­suf­fi­cient load-bear­ing ca­pa­city.

The bonds should not be subjected to tensile strain.
Press firmly to secure the adhesive tape. Ensure there is sufficient back-pressure.
Windproof, airtight or rainproof seals can only be achieved on vapour retarding membranes, roof lining membranes or façade membranes that have been laid without folds or creases.
Ventilate regularly to prevent build-up of excessive humidity and use a dryer if necessary.
