The tube end is crimped down onto the cap sealing portion so that a tube material of the cylindrical tube is disposed within the plurality of annular cap grooves in the cap seal portion to retain the cylinder cap. The cylinder head may have a similar plurality of annular head grooves, with the corresponding tube end being crimped down onto the cylinder head.
