The above subject dairy equipment has been reviewed by Milk Safety Branch and found to comply with the applicable criteria to permit the use of this in-line sight glass in all in-line applications for sight glasses including use in leak detective lines.

This sight glass is available with either a heat resistant glass insert or a high temperature plastic (lexon) insert.

Sufficient copies of this memorandum are enclosed for distribution to state milk control agencies and State Milk Sanitation Rating Officers in your region/district.

FDA's review of this dairy equipment and our finding that they comply with the applicable construction criteria of the Grade "A" Pasteurized Milk Ordinance does not constitute agency endorsement or approval of the dairy equipment and any representation on a label or in any printed literature that they are "FDA approved" would be false.
