Polypipe Manifold Adaptor 1" Female Swivel × 22mm Compression | UFH Stainless Steel Manifold Connection | UFH170 (Pair)
Polypipe Manifold Adaptor 1" Female Swivel × 22mm Compression | UFH Stainless Steel Manifold Connection | UFH170 (Pair)
UFH170 Supplied as Pair 1" F Swivel × 22mm Compression
The Polypipe UFH170 Manifold Adaptor is a brass female swivel adaptor that connects the 1" BSP threaded outlet of a Polypipe stainless steel manifold isolation valve (UFH165) to 22mm compression pipework — the standard supply and return pipe size for most domestic underfloor heating boiler connections. Supplied as a pair — one adaptor for the flow connection and one for the return — the UFH170 is a required fitting whenever 22mm copper or barrier pipe is used to feed the manifold from the boiler. The female swivel design allows the adaptor to be aligned with the pipework run without having to rotate the valve body. These adaptors are specifically required when installing the UFHSPP1 stainless steel manifold control pack.
Where the UFH170 Fits in the System
The Polypipe stainless steel manifold assembly has a specific connection sequence at the boiler supply end. Understanding where the UFH170 sits in this assembly avoids incorrect ordering.
The UFH170 adaptors connect the 22mm supply and return pipes from the boiler to the 1" BSP inlets of the UFH165 isolation valves. Without these adaptors, the 22mm compression pipework cannot be attached to the 1" BSP valve threads. One UFH170 is needed for the flow pipe; the second adaptor (supplied in the pair) connects the return pipe.
Key Features
- Brass construction — durable, corrosion-resistant material compatible with all standard heating system water treatments (inhibitors, scale inhibitors). Suitable for use with copper and barrier pipe systems
- Female swivel end (1" BSP) — threads onto the male 1" BSP outlet of the UFH165 isolation valve. The swivel design allows the compression end to be directed toward the pipework run without the valve needing to rotate, enabling neater pipework alignment in confined manifold housings
- 22mm compression end — accepts standard 22mm copper tube or 22mm barrier pipe with a standard olive and compression nut. Compatible with all standard 22mm compression fittings and pipe systems
- Supplied as a pair — one pack provides both the flow and return adaptors for a complete manifold connection
- Required with UFHSPP1 — specified as a required ancillary when purchasing the Polypipe stainless steel UFCH control pack for 22mm boiler pipework connections

⚠️ Required with UFHSPP1 — Do Not Overlook
The UFH170 adaptors are not included in the UFHSPP1 control pack and must be ordered separately. Forgetting to include these adaptors is a common cause of incomplete manifold assemblies on delivery. If ordering a stainless steel manifold system from scratch — manifold + UFH165 isolation valves + UFHSPP1 control pack — add one pair of UFH170 adaptors to complete the boiler pipework connection.
Frequently Asked Questions
Do I need UFH170 adaptors if my boiler connections are in 28mm pipe?
No — the UFH170 is specifically sized for 22mm compression connections. If your boiler flow and return mains are 28mm, you would need 28mm to 1" BSP adaptors instead (not a standard Polypipe UFH product — consult a plumbing merchant for the correct fitting). Most domestic combi and system boilers use 22mm connections to the heating circuit, so UFH170 is correct for the majority of installations.
Are these the same as the adaptors included in the control pack?
The UFHSPP1 pack includes internal bends and adaptors for connecting the pump and mixing valve within the control pack assembly itself. The UFH170 adaptors are a separate fitting — they connect the assembled control pack/isolation valve combination to the external boiler pipework. Both are required for a complete installation.
