Series 525 Branch Saddle With Male Transition | HDPE × Threaded Male NPT

The Series 525 Branch Saddle with Male Transition from Poly-Cam delivers a robust, multi-level mechanical connection designed for high-performance piping systems. Engineered in the USA, this transition fitting features a hydraulically compressed molded HDPE saddle securely integrated with a threaded metal connection, offering long-term reliability in a wide range of applications.

This transition fitting utilizes a multi-barb design where the natural relaxation of the HDPE pipe creates an initial seal, which is further strengthened under pressure as the internal force enhances contact with the barbs. Even without internal pressure, the compression and tensile strength of the connection surpass stress from thermal expansion, contraction, or relaxation—ensuring a secure, leak-resistant fit.

Key Features:

• Durable Construction: Branch saddle is molded from PE 4710 high-density polyethylene that meets ASTM D3350 and ASTM F714 specifications.
• Threaded Transition Options: Male NPT threads range from 0.5" to 12" and are manufactured to ANSI/ASME B1.20.1 – 2013 standards.
• Mechanical Seal Integrity: Multi-barbed insert creates a strong, pressure-enhanced connection that improves sealing under increasing internal loads.
• Long-Term System Performance: Designed for a 2:1 safety factor at 73.4°F with a 50-year minimum design life.
• Comprehensive Quality Assurance: Poly-Cam fittings meet or exceed ASTM 1598, ASTM 1599, NSF 61 (PM13570), and ARRA requirements.

Installation Notes:

• Follow Plastic Pipe Institute’s guidelines for butt fusion on the HDPE end.
• Use only strap wrenches—avoid pipe wrenches.
• Apply appropriate joint sealant or Teflon tape.
• Always pressure test before backfilling, and compact soil carefully to avoid stress or shifting.

Material Specifications:

• Threaded End: Manufactured from carbon steel (A53/A106), 304/316 stainless steel (ASTM A249/A269), or ERW pipe (ASTM SA-312). Carbon steel is fusion-bond epoxy-coated and meets NSF 61, FDA 175.300, AWWA C116-01, C213-01, UL 262, FM 1120/1130.
