Elektra Microcasa Leva Boiler Knob & Safety Valve

​Elektra Microcasa Leva Boiler knob / cap with built-in safety valve and O-ring.

Fits: All Microcasa Leva versions and models.

Please note: Due to a upgrade to a safer “white brass” compound, this current knob feels different when threading it onto the boiler. It must be tightened more firmly than the previous version or it will not properly seat the compression washer and related o-ring, causing the knob to leak. However, the knob is still made partially of plastic, so do not tighten any more than needed to properly seal.
