We’ve supplied inserts and O-rings to OEM clients for years. After failing to locate a supplier for true “Mil-Spec” components of consistent quality, we sought out top tier injection molding vendors, bought our own molds, and now supply our proprietary solutions that not only meet, but exceed the true current Mil-Spec performance requirements at a great price. Don’t be short changed by US Commercial Grade hardware store or foreign imports of questionable heritage and/or compromised material composition. Everything we supply is Made in the USA from superior grade base materials.
