WARNING

Acetone and methyl-ethyl ketone (MEK) are flammable and their vapors can be

explosive. Repeated or prolonged skin contact or inhalation of vapors can be

toxic. Use a well ventilated area, wear gloves, and keep away from sparks or

flame.

Soften and remove old adhesive, gasket, and insulation residue using acetone or methyl-ethyl ketone (MEK) and

a stiff brush.

Coat the mating surfaces of the metal and gasket or insulation (if applicable) with adhesive (Appendix E, item 2).

Let both surfaces dry until the adhesive is tacky but will not stick to fingers.

Starting with an end, carefully attach the gasket to the metal. Press into firm contact all over.

Touch Up. Should touch up or refinishing be necessary, see TM 43-0139, Painting Instructions for Field Use.

Catches. To replace damaged or missing catches (4), drill rivets out using a drill bit slightly smaller than the diameter

of the rivet body, and secure catch plate with replacement rivets.
