Plastica heat sinks are made to very high standards from Grade 304 stainless steel and are considered the best available. 1 1/2 inch heat sinks are manufactured in flange fitting. All Plastica sinks are full compatible with most heaters.

Please note: If a chemical dispensing unit is "plumbed" into the filtration system, a plastic one-way valve MUST be installed immediately before the dispensing unit, which should be the last component prior to the return to the pool shell. Otherwise serious damage may occur to metallic parts due to the concentrated chemicals when the filter pump is switched off. We do not recommend chlorine tablets to be dispensed in the skimmer basket, as concentrated chemicals will cause damage.
