Sealey Ak522 O-Ring and Seal Pick

Product Information

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). 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 The application parameters should be considered when choosing the appropriate lubricant. The lubricant chosen must be: 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: Regulator hose: swivel end; Piston barrel HP seal; 2nd stage orifIce seal; Valve stem seals; Early Calupso Regulators; Power inflators stems; Sherwood 5121-104,6110-119,6161-101,6121-137, Scubapro 1,050,351, Mares 46110107, Apeks ID: AP1154 Old 1/2-inch NPS valves; 2nd stage inlet fittings; SAS LP seats; J-regulators; HP module seal; Valve HP plugs; 2nd stage barrel and housing plug seals; Paintball Guns; M18X1, 5 Valves, Sherwood 6400-125, 6500-129, Scubapro 1, 050, 160 To get the greatest product, you need to pay attention to the quality of the things you are purchasing.

Then allow it to drop onto the o-ring. Lubrication reduces radial seal installation force and ensures smooth transitions in male and female seals.

Using metal O-ring removal tools, metal tweezers, screwdrivers, or any other sharp metal tools to remove an O-ring can damage the housing of the equipment the O-ring is in. A small scratch in an O-ring groove can create a leak path and adversely affect the integrity of the seal. Benefits of PPE’s O-ring removal tool:

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:

The terms FPM, FKM and Viton® very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material: fluoro rubber. O-rings made of FPM/FKM/Viton® have been the preferred choice for oxygen and nitrox compatibility in SCUBA diving applications. FPM/FKM/Viton® is an elastomer with excellent oil and oxygen resistance at high and low temperatures, very good chemical resistance. Even for use with ordinary air, most experts agree that FPM/FKM/Viton® O-rings outperform common Nitrile O-rings. Upon impact, the o-ring will rebound, and the height of the first bounce will fall into one of four calibrated ranges.

NEW PIERCING – The Bioflex Material is perfect for new belly button rings 14g, it's comfortable and offers great reduction of infection risk. 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. The sealing O-ring in the nose of the DIN connector groove we find on most SCUBA regulator first stages is commonly an SAE AS568 and BS ISO 3601 imperial standard 112 size that is equivalent to 12.37 X 2.62 metric dimensions. In the case of a few regulators (notably Apeks, Atomic, and ScubaPro brands) their groove better accepts the next smaller 111 size O-ring that is equivalent to 10.77 X 2.62 metric dimensions. Both the 112 and 111 size O-rings are very common sizes available in a variety of choices for material and durometer.

Some people believe there is a difference in quality based on colour, but that is more likely attributed to unknowingly using soft dynamic O-rings in static applications. Our O-ring manufacturer states there is little difference in quality for O-rings based on colour alone, and independent testing supports that statement. Some people also incorrectly believe a FPM/FKM/Viton® O-ring can be distinguished from a Nitrile O-ring by the surface appearance. Nitrile O-rings are said to have a shiny surface, and FPM/FKM/Viton® O-rings are said to have a matte surface. This is not a reliable indicator, and certainly not true if the O-ring has been lubricated. How to Replace Your Cylinder/Tank Valve O-ring 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. Figure 5: O-ring measurement: Inner diameter (A), outer diameter (B), and cross-section (C) Determining o-ring material 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.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 Note: As a rule of thumb, the smallest dimension in the specification will be the o-ring cross-section, the largest dimension will be its outer diameter, and the intermediate value is its inner diameter. Lubrication An O-ring is a doughnut, or torus shaped seal typically used to prevent the passing of air or fluid. In other words, O-rings are used to keep fluid or air IN or OUT of a defined space. For example, an underwater camera housing uses O-rings to keep water out, and scuba regulators use O-rings to prevent precious air from escaping.
