This modern type Nitrile 'O' Ring is a direct replacement for E10/E13 rubber ring - when fitted to our own design stainless steel Bevel nuts (Item 0014). and this is listing is for a pack of 3, whcih is the number required per gland nut.

As can be seen from looking at the picture of our vertical tube Bevel Nuts (our Item 0014, but also the type supplied in our vertical bevel tube sets) - the design of these nuts incorporates 1 narrow groove, to hold one O-ring, and one wide groove- to receive two O-rings.  These O-rings are first lightly oiled (I use a similar oil to the oil I will be running the engine on, but not a castor oil . . . which goes sticky after a period of time), and then slid into position in the grooves.  I then lightly oil the inner surface of all 3 O-rings before gently sliding them onto the vertical bevel tube.

We have been manufacturing this design of bevel nut for over 15 years and as well as looking very pretty - this design of nitrile O-ring has meant they are far less likely to leak oil - a common problem with the original Norton design of nuts, which used a single large rubber seal, pushed in tfrom the bottom of the nut.

We have been asked if these nitrile O-rings can be used with original nuts? - well the truth is . . . I never fit original style nuts to my SOHC engines - I always fit this design with our nuts . . . so I cannot say if they can be used or not - but I suspect not, and would think they would have to be fitted to the tube, as the original nut design is open at the bottom.

Sorry - but we do not offer the original design of seal to fit the original type of Norton bevel nut - because almost every original nut we have seen looks either chewed or worn - or rechromed . . . and I am told that design always leaked oil anyway!  We just recommend replacing your original nuts with our design (which also look much prettier once fitted!).

Price is per pack of 3 O-rings, which will fit one ITem 0014 bevel nut
