Sealey Ak522 O-Ring and Seal Pick

Product Information

EPDM O-rings are becoming more common in SCUBA because some people feel it's a safer material for use in breathing air systems. EPDM is a elastomer with excellent weatherability, heat resistance, dielectric qualities and odor-free characteristics. However, EPDM is less resilient and is not recommended for use with petroleum derivatives.

There are three most important factors to keep in mind while deciding on a product: pricing, quality, and popularity.To get the greatest product, you need to pay attention to the quality of the things you are purchasing.

Lubricate the o-ring: Lubricating the o-ring and the groove with a compatible lubricant is critical to ensure it slides into the groove smoothly without any twisting or damage (discussed in depth later in the article).Common regulator piston ring; Body plug seals; Paintball guns, Sherwood 5110-107, Scubapro 1,050,177 The o-ring has a durometer of 70 Shore A. Shore A is a commonly used durometer scale to measure the hardness of rubber materials. The Shore A scale measures the indentation hardness of the material, which is the material's resistance to permanent indentation or deformation caused by a sharp object pressing against it. The higher the number on the Shore A scale, the harder and less flexible the material. A durometer of 70 Shore A means that the material has a medium hardness, with some resistance to deformation under pressure but still capable of some degree of flexibility. O-rings can be made of a very long list of exotic materials and most are inappropriate for SCUBA applications. The materials commonly used in SCUBA applications appear in the following table. Material Clean the o-ring and groove: The groove where the o-ring is installed must be clean and free from any dirt, debris, or previous sealant residue. Also, ensure the o-ring is clean and free from debris or damage. Use a clean, lint-free cloth to wipe the groove clean.
