## Questions & Answers

**Q: Do you have seal ring (blue) for Schedule 40 pipe?**
A: No, couldn’t find a source.  Bought the extra seals bag, but no blue ones, just yellow and orange.

**Q: I have the 6hd2 that came with the s35 seals. i need the s40 for corrugated pipe. can i buy those separately?**
A: Hello, 
I think the 4” corrugated seal is blue.  I couldn’t find one.  Tried modifying an orange and yellow one.  But neither  gave me confidence of a good seal or being able to disassemble.  My plan is to use the yellow one with a RELN adapter (000225) which can well sealed to the corrugated end with tape.  Haven’t installed yet.  Good luck.

**Q: will the hole plugs noted above fit the holes in a concrete distribution box**
A: NO.   These plugs have a narrow ridge that hooks to the inside and outside of the thickness of the Tuf-Tite D box side walls.   With concrete boxes you would need to use hydraulic cement or other type of waterproof chalking to seal the gap.

I just replaced the D box.   It was very old and was never able to keep the root migration out of the joints.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid seal
*by D***W on February 17, 2025*

Used these on the distribuiton box for my septic system i installed. Very easy to use and work great to block the holes that are not needed on the box. Didn’t have any leaks on the box when the tank was filled and drain field was tested for flow rate.

### ⭐⭐⭐⭐⭐ Good product
*by J***H on January 16, 2024*

### ⭐⭐⭐⭐ Super cheap to buy ,cheaply made but works .
*by D***N on October 3, 2024*

Cheap to buy ,cheaply made but works .Definitely would buy it again considering non available and insanely high priced comparable products. If it leaks it just goes imto the ground anyway .But wish a many more riser options were available, not happy with that .
