Sealey Ak522 O-Ring and Seal Pick

Product Information

Choosing the correct o-ring material for a replacement requires consideration of various factors, including the application's operating conditions and the material compatibility with the fluid being used. Several methods are available to identify the material if it has not been initially discovered. Use a rubber indicator test stage inlet fittings; J-regulators; Common in aluminium cylinder valve to yoke regulator, Sherwood 5121-105, Scubapro 1,050,347, Mares 46110211, Apeks: AP1159 The information that follows should help you to know more about the O-rings used in various scuba diving applications. O-Ring Sizing Proper o-ring installation ensures proper sealing of mechanical systems, preventing fluids and gasses from leaking out or entering unwanted areas. Installing an o-ring involves several crucial steps that must be performed carefully to avoid damaging the o-ring or compromising its performance. Here's a general overview of the installation process:

The groove in the Cressi and Poseidon brand regulator DIN connectors measures closest to the original standard, best accepting a BS ISO 3601 metric size O-ring with 11.3 X 2.4 dimensions for which there is no imperial standard equivalent. The M2.4X11.3 size O-ring is uncommon, especially in a material suitable for use with Nitrox. (FYI, the O-ring in Yoke K-valves is easy, it is always an 014 size.) The o-ring is made of NBR; it has an inner diameter, cross-section, and outer diameter of 5.7, 1.9, and 9.5 mm, respectively.Piston seat seal; Survivair manifolds; Power inflator seals; Common in aluminium cylinder valve to yoke regulator seals Sherwood 6400-115, Scubapro 1,050,147, Mares 46110215, Apeks: AP1410 Proper lubrication of the seal before installation is a crucial step in the installation process that ensures the o-ring remains in excellent working condition for an extended period. O Ring Gauge– The instrument allows you to identify the size of almost any O Ring Seal and meets the BS1806 and AS568 Standards.

FLEXIBLE,LIGHT WEIGHT AND COMFORTABLE - Acrylic belly button ring retainer is comfortable, you won’t even notice them when you sleep. FEATURES : belly button rings, belly button rings 5/16, bioplastic belly button rings, clear belly ring, 14 gauge belly button rings General-purpose grease lubricants: General-purpose grease lubricant is excellent for o-ring and elastomer seal varieties used in hydrocarbon service. General-purpose grease lubricant has a recommended service temperature of -29 𐩑C - 82 𐩑C (-20 𐩑F - 180 𐩑F). 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. Used on Small DIN First Stage Regulators (e.g. Apeks and Scubapro), plus some DIN Valve inserts, and Old Yoke Valves If you work on dive gear you know the importance of having the correct O-rings. Many of the O-rings used on cylinders, valves and regulator hoses are pretty much generic. Having a large selection of common O-rings is a must for the serious technical diver.Older internal swivel seal models; AT-PAC BC's Power inflator control Sherwood 6121-122, Apeks id: AP6403 The application parameters should be considered when choosing the appropriate lubricant. The lubricant chosen must be: 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 are normally available with a hardness rating, as measured by an ASTM type-A durometer, of 70 (the "soft" kind) or more rarely a rating of 90 (the "stiff" kind). The soft O-rings are appropriate for dynamic applications where the O-ring is providing a seal with a constantly moving part, such as inside regulators. The stiff O-rings are more durable in static applications where the O-ring is providing a seal with stationary or occasionally moving parts, such as a valve. O-Ring Colour: Used as the Standard for most DIN First Stage Regulators, plus most DIN Valve inserts (e.g. those on the Faber/San-o-Sub DIN/K valves).

In the USA the Society of Automotive Engineers (S.A.E.) publishes AS568B as an Aerospace Standard that specifies sizes for O-rings used in sealing applications. The equivalent British Standards Institution publication is BS1806, which lists all Imperial standard sizes. This standard includes all of the 5 main cross section groups in AS568, plus several sizes that are "between" AS568 sizes. In Australia BS1806 is widely referenced in many industries, including the dive industry. Using a seal material guide will indicate the material the previous seal was made of or which material to choose while replacing the seal. Various sealing materials include NBR, FKM, and EPDM.

Hardness of the o-ring materialAnyone who has to regularly remove and fit O rings on hydraulic, pneumatic or other equipment will know that it can be a fiddly task. The job is made much easier if you have the right tools on hand.
