Pipe Clip Spacers & Support Packers – Imperial and 63mm

Pipe Clip Spacers and Support Packers

These support spacers are used beneath a compatible pipe clip to provide clearance between the clip and its mounting surface. They can help when planning a neat pond filter bay or pipe run where fittings, unions or nearby components need room behind the pipe. Choose the option intended for your clip: 1 inch, 1½ inch or 2 inch imperial, or the separately listed 63mm support packer.

Each selection supplies one spacer or packer. A spacer is not a complete pipe clip and does not grip the pipe on its own. The clip, screw, wall fixing and pipe are separate. Confirm that the spacer and clip bases match before ordering; matching the nominal pipe size is an important first check, but it does not establish that every manufacturer’s clip has the same base or fixing arrangement.

Available options

The stated size identifies the intended clip size. It is not a measurement of spacer height, screw length or the distance that the pipe will stand away from the wall. Those dimensions need to be checked against the actual components used in your installation. The metric packer is listed separately from the imperial spacers; do not assume their bases are interchangeable.

Why clearance behind the pipe matters

A straight pipe can appear to fit neatly against a surface while the larger body of a valve or union does not. Planning the support position with the complete assembly in place helps avoid pulling joints out of line to make them fit. Adequate clearance also makes it easier to inspect joints and reach service connections after installation.

Lay out the pipework before fixing the clips. Include the largest fittings along the run, not just the bare pipe. Check the space needed to loosen union nuts, move valve handles and remove pumps or filter parts. A spacer may help with the support position, but it should not be used to compensate for an incorrectly sized fitting or an unsuitable route.

Choosing the clip and fixing

Compare the clip base, fixing hole and intended support arrangement with the chosen spacer. Our pipe clips provide size options for planning a rigid run, but verify the individual clip and spacer combination before assembly. Do not force a mismatched base together or drill a component in a way that compromises its support.

The mounting surface determines the appropriate screw and anchor. A timber mounting board, masonry wall and thin enclosure panel do not necessarily take the same fixing. Account for the spacer when choosing the fixing length and ensure it still engages the supporting surface correctly. No universal screw size or safe load is specified for an unknown wall and clip assembly.

Support the whole installation

Water-filled pipework is heavier than an empty dry layout. Valves, unions and connected equipment can add local loads, so supports need to be planned around the complete system. Follow the pipe and equipment manufacturer’s guidance on support spacing, movement and fixing points. A small spacer should not be treated as an independent bracket for a pump or filter.

Keep the pipe naturally aligned with its connections rather than drawing it into position with the clips. Misalignment can place unnecessary strain on solvent-weld joints, threaded adaptors and equipment inlets. Check the route both before and after tightening the fixings, especially where a run turns a corner or crosses an uneven surface.

Allow access for cleaning and repairs

A well-supported installation should still be serviceable. Consider a plain pressure pipe union where you may later need to disconnect a section. Leave enough clearance around a double union ball valve for its handle and nuts, and avoid placing a mounting screw where the installed pipe will make it impossible to reach.

If a pipe run serves equipment that is removed seasonally, plan how it will be isolated and drained. Supporting the fixed pipework independently helps keep it in position while a removable component is disconnected. Think about the route of any released water so that maintenance does not direct it onto electrical controls or other sensitive equipment.

Final checks

Before filling the system, check that the clip is properly seated, the spacer bears evenly against its mounting surface and the fixing is secure. Inspect any solvent-welded joints and allow their specified curing time before use. The spacer does not change the adhesive requirements or the pressure capability of the connected pipework.

Recheck the supports with water circulating. Look for movement, vibration or a pipe resting against a neighbouring fitting. If the alignment changes, stop and correct the support arrangement rather than tightening a joint under load. For the pipe itself, see our imperial pressure pipe range and choose the connection system that matches the rest of the installation.
