Description
Water-Soluble Socket-Weld Gap Control
Aquasol SoluGap water-soluble socket weld spacer rings establish a consistent gap during pipe fit-up without measuring or scribing every joint. Three locating tabs keep the ring positioned inside the pipe in upright, sideways or inverted work, while its open centre supports visual alignment.
Choose SoluGap when a temporary spacer is needed for a socket-weld assembly and the residue can be removed during a post-weld aqueous flush. Confirm the project’s required gap, material compatibility and welding procedure before use.
Why Use SoluGap Spacer Rings?
- Repeatable fit-up: standard 1/16 in. (1.6 mm) and 1/8 in. (3.2 mm) thickness options support controlled socket-weld spacing.
- Water-soluble removal: the material is designed to dissolve with water or aqueous steam after welding.
- Stable positioning: three locating tabs help the ring remain in position during assembly.
- Open-centre design: permits a visual check while the joint is aligned and welded.
- Cleaner alternative: avoids leaving a permanent metal spacer in applications where flushing is required.
- Quote-only support: request help selecting size, thickness and packaging for USA or Canada delivery.

Selection Guidance: SoluGap vs. SteelSpace
- Choose SoluGap when the spacer should dissolve during an aqueous post-weld flush rather than remain in the assembly.
- Choose SteelSpace when a permanent 316L stainless steel spacer ring is suitable for the finished joint.
- Choose thickness first: match the 1/16 in. or 1/8 in. option to the specified fit-up gap and welding procedure.
- Then match the nominal size to the socket-weld pipe size.
Simple Installation and Removal
- Confirm the correct nominal size, spacer thickness and approved fit-up requirement.
- Place the ring inside the pipe so the locating tabs hold it at the intended position.
- Align the pipe in the socket, then tack and weld in accordance with the approved welding procedure.
- After welding, use water or aqueous steam as appropriate to dissolve the ring during flushing. It is not intended to dissolve in oil or fuel.
Frequently Asked Questions
How is SoluGap removed after welding?
Use a water or aqueous-steam flush after welding to dissolve the ring. It is not designed to dissolve in oil or fuel.
When should I select the 1/16 in. or 1/8 in. thickness?
Select the thickness that matches the required socket-weld gap and approved welding procedure. If the requirement is unclear, include the application details with the quote request.
Does SoluGap remain in the finished joint?
No. It is intended to dissolve during an aqueous flush after welding, unlike a permanent metal spacer ring.
When should I choose SteelSpace instead?
Choose SteelSpace when a permanent 316L stainless steel spacer is appropriate. Choose SoluGap when water-soluble removal is the better fit for the assembly and post-weld process.
