T-Bolt Clamps - SAE Type “TB”
Murray T-Bolt band clamps are designed to provide connections without leaks. They are typically
installed in truck exhaust or air inlet and water hoses, motorcycle exhaust systems, marine
applications, irrigation system hoses, water pump hoses and filter bags. Band edges are rounded
to protect the hose.
TB series
clamps use a plated steel bolt and self-locking nut. The balance of the components are
made from 300 series stainless steel.
TBSS series
clamps are made entirely from 300 series stainless steel. Clamps are also available in
316 Stainless Steel as special order items.
Maximum service temperature for locknut is 250° (F).
High temp locknuts by special order.
Other sizes are available. Please contact Murray for more information.
