An industry leading range of solutions


O-rings are mechanical gaskets, commonly with round cross sections.  The O-ring creates a seal through compression usually by being seated in a groove of a static or dynamic connection. O-Rings are the most common sealing device used in industrial applications due to their simple application requirements, reliability and cost-effective characteristics.  APG’s extensive range of O-rings is manufactured to AS 568A, DIN ISO 3601 and JIS standards in both imperial and metric sizes and available in a variety of compounds to meet your sealing requirements.  Can’t find the size you are looking for?  Contact APG and ask about our custom vulcanized O-rings that are available to your exact specifications!

O-Ring Cord

O-ring cord is extruded O-ring profile that may be cut to any length and is an excellent solution to large diameter static applications where molded O-rings are impractical.  O-ring cord is sold in custom lengths or may be vulcanized in-house to your specification.  APG offers O-ring cord in an industry leading range of materials and profiles.  APG has been manufacturing custom, vulcanized O-rings, for over 50 years!  Vulcanized O-rings are manufactured by applying thermoset resin, heat and pressure to O-ring cord.  All of APG’s vulcanized O-rings are 100% quality inspected before leaving our manufacturing center to exact ISO9001:2015 standards.


Seals are a vital component of a system to join mechanical systems together and prevent leakage, prevent contamination and/or contain pressure or lubrication. Seals are almost exclusively used on dynamic or rotating applications. APG’s seal range is known for longevity, low friction, and high-speed tolerance even in the harshest of environments. APG offers an extensive range of seals including loaded lip seals, u-cups, rod wipers, t-seals, piston seals and cups, oil seals, v seals, bonded seals, fastener seals, and thread seals. Our seals conform to a range of industry standards including SAE, ARP, JIS, and DIN. Need help specifying the correct seal for your application? Contact the experts at APG today!


APG stocks over twenty different O-ring kits for standard, metric and Japanese Industrial Standard (JIS) applications. APG also offers a large warehouse kit which contains 65 of our top selling O-ring sizes and O-ring cord sizes in both standard Buna and FKM. This kit is contained in a 38-drawer storage box and includes two O-ring picks, a razor blade, cutting and splicing kit and rapid-set adhesive.  Other specialty kits like back up ring kits, flange kits, face seal kits and boss O-Ring kits are available from stock.  Our O-ring splicing kit contains everything necessary for making on-the-job, custom O-rings that eliminate costly downtime.  APG’s field ready gasket kits include our most popular 6 gasket materials and are available in six inch or twelve-inch squares; perfect for your maintenance trucks and MRO departments.

Sheet Materials

Stocking over 500,000 linear feet in over 100 different gasket materials, APG is able to supply bulk gasket material orders to our distributor, OEM and gasket fabrication customers today!


Gaskets are mechanical seals used to prevent leakage in static applications between two or more mating surfaces. Gaskets are produced from sheet materials in various raw materials including non-asbestos sheet, paper, rubber, cork, felt, neoprene, fiberglass, metal, silicone, or PTFE (Teflon). Gaskets are the trusted solution for static seals where high compression performance is required. Spiral-wound gaskets are a hybrid composite of metallic and flexible graphite specifically used in low clamp force applications. APG provides sheet gaskets, manifold gaskets, spiral-wound gaskets, ring gaskets, electrical gaskets, pipe gaskets, and flange gaskets. Don’t see what you are looking for?  APG provides custom gaskets manufactured from a leading range of gasket raw materials.

Packing Material

Packing is a sealing component used in stationary applications and are used to provide a compression seal.  APG offers a wide range of packing materials for use in pump, valve and sanitary applications including: braided, square braided and general service packing, GFO®Packing, inconel wire packing, graphite filament packing, carbon yarn packing, TFE packing (Teflon®) and eco-friendly vegetable fiber packing.


APG offers a large selection of sealing accessories and tools including measuring devices for O-rings, O-ring tools and lubricants.  We also offer thread sealant tapes, packing and gasket tools, and punch kits.
