Bowman Tubestack O-Ring for 5113 Heat Exchanger

As a retailer of hot tub spare parts and pool equipment, I supply genuine Bowman heat exchanger replacement seals. This tubestack O-ring provides the critical seal for the Bowman 5113 heat exchanger tubestack assembly.

Essential Sealing Component

The tubestack O-ring creates a watertight seal between the tubestack and the heat exchanger housing. This seal prevents water leakage and ensures proper heat transfer by maintaining separation between the heated and cooled water circuits within the heat exchanger.

Compatible Model

Bowman 5113 Heat Exchanger – This O-ring is precisely sized for the 5113 model tubestack assembly.

When Replacement Is Needed

Replace the O-ring when you notice: water leaks from the heat exchanger housing, reduced heating efficiency, visible O-ring damage or deterioration, compression set (permanent flattening), cracking or hardening of the rubber, or during routine heat exchanger servicing. O-rings are consumable parts that require periodic replacement to maintain seal integrity.

Installation Guidelines

Clean all sealing surfaces thoroughly before installing the new O-ring. Remove any debris, old lubricant, or scale deposits. Apply appropriate silicone-based lubricant to the O-ring before installation – this aids fitting and ensures proper sealing. Avoid petroleum-based lubricants which can damage O-ring materials.

Check the O-ring seating groove for damage or corrosion that might compromise the seal. Install the O-ring carefully without twisting or stretching excessively. Tighten housing connections gradually and evenly to manufacturer specifications.

Regular Maintenance

Inspect O-rings annually during system servicing. Replace O-rings whenever the heat exchanger is disassembled for maintenance, even if they appear serviceable. The minimal cost of preventive O-ring replacement is far less than addressing leaks and potential water damage from failed seals.

Genuine Bowman Component

Authentic Bowman O-rings are manufactured from materials specifically selected for heat exchanger applications, offering proper temperature resistance, chemical compatibility with pool water and additives, and the correct hardness and dimensions for reliable sealing.
