Alternative O-rings for JUAL's ø50, ø63, ø75 and ø90 Roof Outlets.
The rings in these bags are used as thicker or thinner alternatives to the O-rings that come with JUAL Roof Outlets as standard.
O-rings are generally used for sealing when roof outlets are inserted in drainpipes with larger diameters. The O-rings in these bags are used when there is a need for thicker or thinner alternatives to the O-rings which are supplied with our roof outlets as standard.
Each bag contains 3 x 10 O-rings with three of the following four thicknesses: ø6, ø8, ø10 and ø12. O-rings with the remaining fourth thickness are supplied along with the JUAL Roof Outlets.
