Rubber Sleeve for Perforated Flask

SKU# 211.070X


No more messy masking tape! These latex rubber sleeves are placed over the flask to contain the investment while pouring and also form a collar so that no spilling occurs. Dimensions listed are for the flask that each sleeve will fit. Sleeve must be removed prior to burnout. Warning: DO NOT USE if you are NRL latex sensitive.

Please note: Our sleeves are black rubber, not white like in the photo.
