Product range

Core HVAC accessory categories for mechanical systems.

HVAC fittings are grouped clearly for consultants, contractors, and procurement teams reviewing submittals, BOQs, and project alternatives.

Connections

Unions and Flanges

Dielectric unions and flanged unions that break the galvanic path where steel meets brass or copper. Threaded 1/2" to 2" at 25 bar; flanged 2-1/2" to 8".

Suitable for plantroom and branch connections
Useful in mixed-material systems
Clean product grouping for BOQ review

Air removal

Air Vents

Automatic brass air vents with an integral check valve for the high points of closed-loop systems, rated 15 bar and 120°C.

Helps improve hydronic efficiency
Supports easier commissioning
Clear offer for consultant and contractor review

Specifications

Matched to the pressure class and fluid class the job calls for.

Accessories are specified against the consultant schedule, pressure class, connection type, and material, with alternatives offered when availability or value engineering is relevant.

Applications in Kuwait

HVAC accessories for hydronic systems that need to commission cleanly.

These components sit in the small details of the mechanical system, but they affect commissioning, air removal, service access, and long-term maintenance for chilled water and heating loops.

Selection data

Air vents, dielectric unions and connectors — the sizes and ratings a schedule asks for.

TEMBO automatic air vents in Kuwait come in 3/8″ and 3/4″ connections, rated 15 bar and 120 °C in a full brass body; dielectric unions cover 1/2″ to 2″ threaded at 25 bar and 82 °C and 2-1/2″ to 8″ flanged at 12.1 to 16 bar. Match the accessory to the pressure class of the circuit and to the metals on either side of the joint — this is the table we check a BOQ against before quoting.

HVAC accessory selection by circuit

Ratings from the TEMBO datasheets; full pattern and size codes are on each product page.

Accessory	Sizes	Rating	Where it goes
Automatic air vent, full brass (TGAA)	3/8″ and 3/4″ connection; 1/2″ MPT check valve supplied	15 bar · 120 °C	High points of chilled and hot water loops, pump headers, coil returns, pressurisation sets
Dielectric union, threaded (TGDEU)	1/2″ – 2″ in six patterns: FPT or MPT iron × FPT, MPT or solder-end brass	25 bar · 82 °C	Steel-to-brass and steel-to-copper joints at FCUs, coils, calorifiers and pumps
Dielectric flanged union (TGDEF / TGFF)	2-1/2″ – 8″	12.1 bar welded patterns · 16 bar female × BPT · 82 °C	Plantroom headers and equipment connections between steel and bronze above 2″
Flexible pipe connector, EPDM bellows or stainless braided (TGTFC)	Flanged pump, chiller and AHU tails	EPDM bellows to 20 bar	Vibration break and misalignment take-up at rotating plant

Chilled water, LTHW, condenser and pressurisation circuits are all within the 82 °C limit of the unions and the 120 °C limit of the vents. For steam or above 82 °C, ask before specifying — the answer is usually a different union material rather than a different accessory.

Frequently asked questions

Common HVAC accessory questions.

Quick answers for project teams buying hydronic unions, air vents, and related HVAC accessories.

01Do you supply HVAC accessories for chilled water systems?

Yes. We supply HVAC accessories for chilled water, LTHW, condenser water, and pressurisation circuits, including hydronic unions and automatic or manual air vents.

02Can you match the accessories to a consultant schedule?

Yes. Send the HVAC accessory schedule or BOQ and we can match pressure class, connection type, material, and available alternatives for approval.

03Why are air vents important in hydronic HVAC systems?

Trapped air reduces heat transfer, creates noise, slows commissioning, and can affect pump performance. Correctly placed air vents help the system run cleaner and more reliably.
