The Rexton Quick Dry BTE Thin Tube (size 3.3.0.D) is a genuine replacement tube for Rexton behind-the-ear (BTE) hearing aids, sold in a convenient 10-pack. This tube is compatible with Rexton BTE and M-CORE B-LI M/P hearing aid models available at Costco Hearing Aid Centers.

These thin tubes connect the behind-the-ear hearing aid body to the ear canal, delivering amplified sound discreetly and comfortably. The 3.3mm diameter tube in size 0 is designed for users who need a specific tube length to achieve the correct fit and routing around the ear. The "Quick Dry" design helps moisture escape, reducing buildup and maintaining consistent sound quality. Tubes should be replaced every 3 to 6 months or when they show signs of hardening, cracking, or discoloration to maintain optimal performance. The 10-pack provides a sufficient supply for regular maintenance.
