Rubber Union Seal 4″ The Rubber Union Seal 4″ is a replacement sealing ring designed for compatible 4″ union fittings used in dairy, milk handling, wash and processing pipework. It helps create a secure seal within the union connection, supporting reliable flow and reducing the risk of leaks during regular use. Union seals are important where pipework connections need to remain tight, serviceable and easy to dismantle for cleaning, inspection or maintenance. If the original seal becomes worn, flattened, split, swollen or damaged, the joint may no longer seal correctly and the system may suffer from leaks, poor alignment or product loss. Replacing it with the Rubber Union Seal 4″ helps restore dependable sealing and supports consistent pipework performance. This rubber seal is useful for dairy farms, engineers, small producers and service teams carrying out repairs, refurbishment or planned maintenance on compatible 4″ union fittings. It is particularly suitable where the union body remains serviceable but the seal requires replacement due to age, wear or routine servicing. Keeping spare union seals available helps make pipework maintenance quicker and reduces avoidable downtime. Th
