Whether you call them enema nozzles, enema tips or rectal nozzles, this is the part of the enema kit that will be inserted into the rectum. Because we know everyone's needs and comfort levels vary, we offer a variety of enema nozzles in different materials and shapes. Our medical-grade silicone enema tips are soft, non-toxic and can be re-sterilized in boiling water. Medical plastic nozzles are hard and therefore may be easier to insert. Or you may prefer a soft vinyl tip. Also consider the shape of the rectal nozzle - straight, tapered or retention models, which are designed to plug the opening of the rectum without squeezing your sphincter muscle, making for a more relaxing enema experience.
