High-Quality Range Of LPG Wall Blocks & Fittings
Our wall block fittings range includes all essential components used to connect, secure, and test LPG installations safely and efficiently.
Wall Blocks
Wall blocks are the core mounting points for LPG systems, supporting regulators and cylinder connections. BES supplies both the Single Wall Block and Double Wall Block models, providing options for single-cylinder or twin-cylinder installations. These robust brass fittings are engineered for durability and easy wall mounting.
Changeover Valves
The Manual Changeover Valve enables manual switching between two gas cylinders, ensuring continuous supply in twin-cylinder systems. Commonly used with wall-mounted regulator assemblies, it provides safe and controlled management of LPG flow during cylinder replacement or maintenance.
POL Connectors, Tails & Nuts
POL (Prest-O-Lite) connectors and tails provide secure, high-pressure connections between LPG cylinders and regulators. BES offers components such as the Propane Tail – POL x ¼" BSP M, Propane Connector – POL x ¼" M, and POL Nut, all designed for precision fit and leak-tight performance. W20 Nuts and W20 Elbows are also available for interconnections between regulators and pipework where threaded alignment or angular positioning is required.
Tee Pieces
Tee fittings allow branching of gas supply lines for multiple cylinder or regulator configurations. Our range includes the Clesse Tee Piece W20, POL Extended Tee Pigtail, and Y POL Tee, along with the Propane Changeover Kit Tee Piece (M x M x F W20).
Test Point Adaptors & Nipples
Testing is a crucial part of LPG installation safety. BES stocks the popular Gas Test Point Adaptor and High Pressure Test Point Nipple, both designed for accurate system pressure checks.
Spanners & Washers
To support correct installation and maintenance, BES supplies POL Nut Spanners in both forged steel and zinc-plated pressed steel versions and spare nitrile and aluminium washers compatible with changeover kits and POL connectors, ensuring continued leak-free operation and easy replacement during service work.
Cylinder Adaptors
The Gas Cylinder Adaptor is a top choice in our range, enabling the connection between differing thread standards and providing flexibility across various LPG cylinder types and fittings. It ensures compatibility within mixed-system setups and simplifies field replacements or conversions.
Installing LPG Wall Blocks & Fittings
When fitting LPG wall blocks, ensure the mounting surface is flat, solid, and capable of supporting the assembly’s weight. Blocks should be fixed securely using appropriate wall anchors or screws, with pipework aligned to avoid strain on joints. All fittings must be tightened using the correct spanner to manufacturer torque recommendations. After assembly, perform a full leak test at working pressure before placing the system into service. For safety, installation and maintenance of LPG systems must always be carried out by a Gas Safe registered engineer qualified for LPG work.

Wall Blocks FAQs
What are LPG wall blocks used for?
Wall blocks are used to mount LPG regulators and fittings securely to a wall or stable surface, creating a fixed connection point for single or twin-cylinder systems.

Yes. The fittings supplied by BES are compatible with standard LPG cylinders, including propane and butane, provided the correct connector type (such as POL) is used.
What’s the difference between a single and double wall block?
A single wall block supports one cylinder, while a double wall block allows for two-cylinder setups where a changeover valve or dual-regulator arrangement is required.
Do I need to use a specific type of washer for LPG fittings?
Yes. Always use the washer type specified for your connector, typically nitrile or aluminium, to ensure a gas-tight seal.
