Seagull Viton 75 O-Ring Imperial BS310V 0.475 x 0.210 in (12.07 x 5.33 mm)
Available
Seagull Viton 75 imperial O-rings, BS300 series, in 42 sizes (BS309V to BS350V). Inside diameters run from 0.412 in (10.46 mm) to 4.600 in (116.84 mm), and the cross-section is 0.210 in (5.33 mm). Each ring is Viton (FKM), 75 hardness.
The model code is the BS 1806 size number with a V for Viton: for example BS330V is a 2.100 in (53.34 mm) inside diameter ring with a 0.210 in (5.33 mm) cross-section. The option list shows the nominal inside diameter as the nearest common fraction of an inch; the exact inside diameter is in the sizes table.

Model codes are the Seagull size codes (BS 1806 size numbers with a V for Viton); the SKU is the AIMS part number.
Selecting the right option
O-rings are specified by inside diameter and cross-section. In this series the model code (BS309V to BS350V) is the BS 1806 size number, which fixes both dimensions, so if you know the BS number you can go straight to it in the options list.
If you only have the ring or the groove, measure the inside diameter and the cross-section of an unused ring and match them to the sizes table. A ring with the right inside diameter but the wrong cross-section will not seal correctly.
Viton (FKM) is chosen where NBR is not suited to the fluid or the operating conditions. It is not suited to every fluid, so check the compound against your fluid before ordering.
If the size you need is not listed, send AIMS the inside diameter and cross-section and we will check what is available.
Fitting and use
Check the ring is the right size for the groove, keep it clean, and lubricate it lightly with a lubricant compatible with the compound before fitting.
Slide the ring over threads, keyways, splines and sharp edges using a sleeve, tape or a lead-in chamfer so it cannot be cut, and avoid twisting or rolling it into place.
Do not over-stretch the ring to fit, and replace O-rings when a joint is stripped down rather than reusing them.
