Series 700 The Series 700 features either a TFE* or FED** seamless liner that extends through the body of the expansion joint to the outer edge of raised flange faces. The liner is fused to the body when the joint is cured. This type of construction provides ultimate protection against chemicals seeping or leaking. An optional…
MASONFLEX In 1976 we introduced our first spherical expansion joints, under the name “MASONFLEX”. Although we had higher burst pressures than the other manufacturers, our technical literature still made people aware that Nylon reinforcement had to be derated at higher temperatures. MASONFLEX connectors did not always require control rod protection as the lengths at given…
Series HT700 Invincible Series HT700 combines all the construction and performance advantages of the 700 with high temperature resistance. Reinforced with high temperature resistant fabric, and with the cover of either EPDM or Viton, the HT700 can provide full pressure service at operating temperatures up to 350°F and 400°F respectively.

SAFEFLEX Safeflex expansion joints are molded and vulcanized in hydraulic presses. This high pressure process produces a smooth finished product with outstanding adhesion between the cover, reinforcement and tube. Most of our competitors still use Natural Rubber impregnated Nylon tire cord between sulfur cured, EPDM covers and tubes. This construction becomes brittle with age at…
Series 450 Mercer Flexmore Series 450 is the most economical, full-pressure elastometric expansion joint available. Tough fabric and tirecord plies are bonded between the tube and cover in a steel mold and then cured in a thermostatically controlled steam chamber. The product is uniform in both appearance and performance. A wide, low profile arch provides…
Series 500 The Invincible 500 is our most rugged expansion joint. They are all hand built by our skilled craftsmen. The 1/4” minimum thickness solid elastomer tube is continuous with the flange face. Multiple plies of rubber impregnated high strength polyester or nylon tire cord form the first pressure reinforcement over the tube. Arch swell…
Series HT500 The Invincible HT500 has all the construction features of the 500 combined with High Temperature capability. DuPont Kevlar® or other heat resistant fabrics replace the polyester or nylon. The tube and cover are either EPDM or Viton® for full pressure service up to 350°F and 400°F respectively Product Documentation
Series 600 The Invincible 600 has a built in solid steel ring locked in place by reinforcement materials at the arch crown. This enables the 600 to handle vacuum conditions in excess of those listed for the 500 in multiple arch joints. Product Documentation

Series 1000 Expansion joints installed in piping systems that are anchored on both sides of the joint. No control rods are necessary. If control rods are installed as a safety measure, the locking nuts must be backed off with a clearance equal to the specified axial movement. The expansion joint will exert a thrust force…
