Can it be hot filled at about 165f?
No, this bottle is not recommended for hot fill at 165°F. This 16 oz square bottle is made from standard PET, which is typically intended for cold-fill or ambient-fill applications, and the product listing does not indicate that it is rated for hot-fill use. For hot-fill applications, a hot-fill–rated PET bottle is required to withstand elevated temperatures without paneling or distortion.
