This testing device comprises of a tube containing a specific magnitude weight (Figure 6 labeled A). The weight descends a predetermined distance for each material, as shown on Figure 6. 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. 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. The ISO 12209 standard specification for dimensions of the O-ring groove in the nose of the 232 bar and 300 bar DIN connectors for compressed air has an inside dimension of 12 mm and an outside dimension of 17 mm. In 2003, the standard depth for the groove was revised from the original 1.9 mm to a slightly deeper 2 mm. The specification for the sealing O-ring itself is an inside diameter of 11.2 mm with a cross section of 2.65 mm. From what we have been able to determine, not all SCUBA regulator manufacturers seem to use the current standard groove and O-ring in the universal DIN fittings found on their first stages.

O Ring Gauge– The instrument allows you to identify the size of almost any O Ring Seal and meets the BS1806 and AS568 Standards. 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. Older internal swivel seal models; AT-PAC BC's Power inflator control Sherwood 6121-122, Apeks id: AP6403 Extraction and Insertion damage is reduced. Using metal objects to remove O Rings can cause damage to the housing and equipment which then create a leak path that affects the integrity of the seal 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:

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 O-rings are measured by their inside, outside, and cross-sectional diameter. O-ring measuring tools like rulers or calipers can be used for these measurements. What is an o-ring installation tool? Common regulator piston ring; Body plug seals; Paintball guns, Sherwood 5110-107, Scubapro 1,050,177 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. Position the testing device over the o-ring and lift the weight to the topmost point of the tube. Then allow it to drop onto the o-ring.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.

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.

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 The milky white O-ring occasionally seen in the face of K-valves, sometimes called a 10,000 psi O-ring, is made of Polyurethane. Polyurethane is very abrasion-resistant, but it is sensitive to UV light (sunlight). 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.

Upon impact, the o-ring will rebound, and the height of the first bounce will fall into one of four calibrated ranges.

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). In the European Union nations, the EN 144-3:2003 standard requires a valve outlet known as M26x2 to be used on dive cylinders containing oxygen or Nitrox mixtures with greater than 22% oxygen. The M26x2 outlet is similar in appearance but slightly larger than the standard DIN outlet, and thus incompatible with the standard DIN connector found on SCUBA regulators. The purpose of this incompatible valve outlet is to force the dedication of cylinders, regulators and fill stations to Nitrox use. The sealing O-ring in the nose of the M26x2 connector is 13.9 X 2.6 metric dimensions, equivalent to the 113 size. The M26x2 outlet and connector for Nitrox and oxygen is very rarely seen outside the EU. O-rings Available from The Scuba Doctor To get the greatest product, you need to pay attention to the quality of the things you are purchasing. 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.

Console/gauge hoses: male end; Underneath filter; Hose adapters; HP seat seal; LP swivel cap; HP port plugs, Scubapro 1,050,145, Mares 46110108, 46110110, Apeks: AP1445 Used on Small DIN First Stage Regulators (e.g. Apeks and Scubapro), plus some DIN Valve inserts, and Old Yoke Valves 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. Figure 6: Rubber indicator test: Weight (A) and o-ring (B), Ethylene Propylene (E), Nitrile (N), Kalrez (K), and Viton (V) Use a seal material guide 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.
