Hegen Replacement Seal (4 Pack) - Compatible with Hegen Baby Bottles - Durable Leak-Proof Silicone Seals for Freshness - Perfect for Travel, Daycare & On-the-Go Feeding

Silicone seals are sold separately as replacement seals for our breast-pump funnels, storage lids, spouts and adapters. We recommend replacing these seals every 3 months or at first signs of wear and tear. A key component in our Express-Store-Feed series, these seals allow our containers to be converted into air-tight and secured storage bottles, minimizing the oxidation of precious nutrients and keeping its contents fresh.
