We help industries solve sealing problems. The marketplace needed easier access to a broader range of seal inventory than was generally available, expert advice, and extensive manufacturing capabilities. We listened to customers and put it all under one roof. We’ve developed one of the largest inventories of hydraulic, pneumatic, and general industrial sealing components in the nation, operated by a team of friendly seal experts, and a factory that molds and machines both plastic and rubber. Custom, same-day sealing solutions are routine for us. AY Seal & Packing provides its employees with rewarding, secure employment in a can-do culture. Our employees take an interest in our customers, and we take an interest in our employees.

all us FIRST!

Are you routinely back-ordered when buying your hydraulic seals? Many seal customers need seals now and if they can’t get what they need immediately, they have to make a second call; or a third. That requires time (money) and perhaps a second shipment (more money).
Step 1. Compare our list price.
Step 2. Compare your discount off of list price. Your NET PRICE is likely lower than our competitors.
Step 3. Compare your shipping costs using our UPS account. In 2016, AY Seal & Packing negotiated a deep discount with UPS.
Step 4. Compare our inventory. AY Seal & Packing has the broadest seal inventory in the business. Just ask around.
