Watts Radiant RadiantPEX-AL 3/8" Diameter 200' PEX-AL-PEX tubing
Watts Radiant RadiantPEX-AL 3/8" Diameter 200' PEX-AL-PEX tubingRadiant PEX-AL is a composite pipe engineered for radiant floor heating. It's proven, long lasting and maintenance free. Installers like it because it's lightweight, durable and can be shaped to fit any jobsite. The aluminum layer protects boiler systems against corrosion and it has superior temperature and pressure ratings. RadiantPEX-AL pipe and fittings are manufactured to American Standard Testing Methods for requirements and test methods for materials, workmanship, dimensions, environmental stress, cracking, sustained hydrostatic pressure strength, thermo-cycling resistance and bend strength, among other tests. RadiantPEX-AL meets or exceeds these specifications.$72.22 -
Johnson 24VAC Single Stage Temperature Control
Johnson A419GBF-1C 24VAC Single Stage Temperature ControlThe A419 series controls are single-stage, electronic temperature controls with a Single-Pole, Double-Throw (SPDT) output relay. They feature a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display (LCD) for viewing the temperature and status of other functions. A Light-Emitting Diode (LED) indicates the controls? output relay On/Off status. The A419 controls are available in 24 VAC or 120/240 VAC powered models. The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset function. The setpoint range is -30 to 212°F (-34 to 100°C). The controls feature remote sensing capability and interchangeable sensors. The A419 controls are available in either NEMA 1, high-impact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X watertight, corrosion-resistant surface-mount enclosures.$74.63 -

Caleffi 132 Series QuickSetter Balancing Valve with Flow Meter
Balancing Valve with Flow Meter, offers direct reading of flow rate, no sight gauge clouding or scaling. Has brass valve body and flow meter, rotatable valve for flow rate adjustement, and graduated scale flow meter with magnetic movement flow rate indicator. MAX working pressure: 150 psi. Temperature range: 14-230 F. Max percentage of glycol: 50%.The 132 series balancing valve accurately sets the flow rate of heating and cooling transfer fluid supplied to fan coils and terminal units or where flow balancing is required in solar thermal systems. Proper hydronic system balancing ensures that the system operates according to design specifications, providing satisfactory thermal comfort with low energy consumption. The flow meter is housed in a bypass circuit on the valve body and can be shut off during normal operation. The flow meter permits fast and easy circuit balancing without added differential pressure gauges and reference charts. The balancing valve is furnished with a preformed insulation shell to optimize thermal performance or both hot and cold water systems.$90.32 -
Caleffi Discal Series 551 Air Separators Brass Sweat
Air separator. Brass body. Glass reinforced nylon internal element. ½" NPT female bottom thread. Max. working pressure: 150 psi. Working temperature range: 32—250°F.In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.$91.57 -
