Description

Pentair 152030 W34-OR Buna-N O-Ring for 3/4" Standard Housings
A replacement Buna-N sealing O-ring used on select Pentair/American Plumber/Pentek 3/4" standard filter housings to help maintain a leak-tight seal between the housing components.

Key Features:
  • Buna-N (nitrile) O-ring for 3/4" standard filter housings (as named/listed)
  • Product type: O-Ring
  • Type: Standard
  • Size: 3/4"

Compatibility & Applications:
  • Listed "Used With" housing models: WV34, WVC34, W34-PR, WC34-PR
  • The related 3/4" standard housing family on the manufacturer site is described as having a 3/4" NPT threaded connection and commonly includes a pressure relief feature on applicable caps (housing family info)
  • Must only be used where the manufacturer specifies this exact part number: 152030 (W34-OR)

Installation & Operation Notes:
  • Installation should be performed by a qualified plumber/technician (or an experienced homeowner) following the housing's service instructions
  • Before opening a filter housing, use the housing's pressure relief feature (if equipped) and follow safe depressurization and shutoff practices per the housing/service documentation
  • Confirm the O-ring is fully seated (not twisted) and the sealing surfaces are clean before reassembly

Maintenance & Troubleshooting:
  • This O-ring is commonly replaced to address leaks at the housing seal or when the existing O-ring is worn, flattened, or no longer sealing reliably
  • If the housing still leaks after replacement, verify the O-ring is correctly seated and that the cap/sump sealing surfaces are clean and undamaged
  • User feedback strongly emphasizes using silicone plumber's grease (and avoiding petroleum-based lubricants) because petroleum products can cause O-rings to swell

User Reviews & Q&A Summary:
  • Feedback most often describes it as a perfect/correct fit for 3/4" standard housings (including Pentair/Pentek "blue" standard housings) and as restoring a tight seal
  • Common tips from reviewers include lubricating with silicone grease (not petroleum-based) and treating the O-ring as a routine replacement item during filter cartridge changes
  • A small amount of mixed feedback notes it may not feel like the "best fit" in one user's setup but still worked as a seal

Most Liked Positive Review

Fits perfectly!

This perfectly fits my Pentair Pentek Blue standard water filter housing and is very high quality. IMPORTANT TIP: Use silicone plumber's grease on it, rather than petroleum-based lubricants (which almost all plumbing greases and thread-seal compounds contain), as they will make the o-ring swell. Also, a good practice is to use a new o-ring ever time you change water filter cartridges.

Great to have a company that has what I need.

I have a water filter that has a 0 ring size not available in my area. The manufacturer of the filter gave me the part number. Your service person was great to get the product to me. Thank you.

W34-OR, BUNA-N O-ring for 3/4" Standard Housings

Great Product, Great Price, Delivery was messed up, it was scheduled for one day and it took 4 days. Not Supply House, it was UPS's mistake. The people and website at Supply House were great. Thank you, Mark

Correct fit.

Works like it is supposed to....Only thing....It could have, should have, been posted in an envelope to save a BUNCH on postage. It cost more in postage than item.
