Praher 2″ MPT × 2″ Slip High‑Temp Union with O‑Ring | 200‑906

The Praher 200‑906 is a high-temperature, full‑flow union fitting designed to connect a 2″ male pipe threaded (MPT) port to a 2″ slip (socket) connection on pool or spa systems. Featuring an EPDM O‑ring seal and heat-resistant polymer construction, it enables efficient plumbing service while resisting thermal stress and eliminating the need for thread sealants.

Key Features:

• 2″ MPT (threaded) × 2″ slip (socket) connection for compatibility with common pump ports and PVC pipe
• High‑temp polymer body designed to withstand heat buildup during pump dry running
• EPDM O‑ring sealing system delivers reliable, leak-free connections without sealant
• Full‑flow union design minimizes pressure drop and maintains optimal circulation
• Durable gray PVC construction resists corrosion and chemical exposure

Technical Specifications:

• Manufacturer: Praher Plastics Canada Ltd.
• Part Number: 200‑906 (Catalog: 9175‑92)
• Connection Sizes: 2″ Male Pipe Thread × 2″ Socket (slip)
• Material: High‑temperature polymer / Schedule‑80 PVC
• O‑Ring: EPDM
• Max Service Temperature: ≈ 80 °C (176 °F) at ≤ 3.5 bar (≈ 50 psi)
• Pressure Rating: ~50 psi (at high temp); some listings up to 150 psi at room temperature

This union is engineered for installation at pump volutes or suction ports where heat buildup is common, especially if the pump is starved of water flow. The design helps prevent thread cracking and seal failure during hot operation and allows future pump servicing without cutting pipe or using thread sealants.

Installation Tip: Screw the threaded end into the pump port and glue the slip end into the PVC plumbing. Apply a small amount of pool-rated lubricant on the O‑ring for easier assembly and to ensure a tight, leak-free seal. Inspect the O‑ring and union nut periodically for wear and replace as needed to maintain performance.
